Insulin and Glucagon | Physiology | Biology | FuseSchool
In this lesson, you will learn about how your blood glucose level is regulated (or controlled) by two important hormones – insulin and glucagon, via a negative feedback system.
When you consume a meal that is high in carbohydrates, such as rice, pasta, and bread, this will cause your blood glucose level to increase. Carbohydrates are essentially long chains of repeating glucose monomer units, much like beads on a necklace.
During digestion, this is broken apart into glucose, which absorbed into our bloodstream. This increased blood glucose level causes a gland known as the pancreas to secrete a hormone called insulin. Remember that a gland secretes hormones which act on specific target organs.
In this case, the target organ is y...

Regulation of Blood Glucose || Glucose Homeostasis || Biochemistry
Blood glucose homeostasis - This is the video on blood glucose regulation. Blood glucose regulation is occurring two stages. Fasting and postprandial stage.
Blood glucose is regulated by three important factors:
1. Hormones (Glucagon (Hyperglycemic) and Insulin (hypoglycemic hormones))
2. Metabolic Processes
3. Renal Mechanism.
Normal fasting blood glucose is 70-100mg/dl
and normal Postprandial blood glucose is upto 140mg/dl

Blood glucose regulation involves maintaining blood glucose levels at constant levels in the face of dynamic glucose intake and energy use by the body. Glucose, shown in figure 1 is key in the energy intake of humans. On average this target range is 60-100 mg/dL for an adult although people can be asymptomatic at much more varied levels. In order to maintain this range, there are two main hormones that control blood glucose levels: insulin and glucagon. Insulin is released when there are high amounts of glucose in the bloodstream.
Glucagon is released when there are low levels of gluco...

Insulin and Glucagon | Physiology | Biology | FuseSchool
In this lesson, you will learn about how your blood glucose level is regulated (or controlled) by two important hormones – insulin and glucagon, via a negative feedback system.
When you consume a meal that is high in carbohydrates, such as rice, pasta, and bread, this will cause your blood glucose level to increase. Carbohydrates are essentially long chains of repeating glucose monomer units, much like beads on a necklace.
During digestion, this is broken apart into glucose, which absorbed into our bloodstream. This increased blood glucose level causes a gland known as the pancreas to secrete a hormone called insulin. Remember that a gland secretes hormones which act on specific target organs.
In this case, the target organ is your liver, which is stimulated to convert glucose to glycogen.
Glycogen is basically long, multi-branched chains of glucose monomers, stored in liver and muscle cells. Insulin also causes your body cells to uptake (or take in) glucose. So this decreases your blood glucose level back to its optimal state.
When this system is faulty, this leads to a medical condition known as diabetes – if you want to learn more about diabetes, this will be addressed in another video. The same response also occurs when you consume foods and drinks high in sugar such as sweets, cakes, and fizzy drinks.
When your blood glucose level drops, such as when you are hungry, the pancreas secretes a hormone called glucagon. Like insulin, the target organ for glucagon is also the liver, though it stimulates the opposite process – the breakdown of glycogen into glucose. This increases your blood glucose level back to its optimal state.
To review, insulin and glucagon are two hormones released by the pancreas, which act on the liver to regulate our blood glucose level.

Proteins are responsible for nearly all bodily and cellular functions: from structural proteins in bones; contractile proteins in muscles; transport proteins in blood plasma; to hormones, antibodies, cell receptors, ion channels, and enzymes that catalyze almost every chemical reactions in biological systems.
Proteins are polymers of amino-acids linked together by peptide bonds. An amino-acid consists of an amino group, a carboxyl group, and a unique side chain, connected to a central carbon, the α-carbon. Instead of being an extended chain of amino-acids, a protein usually folds into a three-dimensional conformation that is critical for its functions. The structure forms as a result of interactions between the side chains of amino-acids, and is thus dictated by the amino-acid sequence.
Of the 20 amino-acids that make up proteins, nearly half are essential, meaning the body cannot synthesize them and must get them from the diet. Animal proteins are usually considered high-quality, complete proteins, because they have similar amino-acid composition as human proteins, and can thus provide all the required amino-acids, but a combination of a variety of plant foods may also do the job.
Proteins in foods are digested in the stomach and small intestine, by the action of stomach acid, which denatures proteins, and several enzymes that hydrolyze peptide bonds. Together they break down proteins into individual amino acids, which are then absorbed into the bloodstream and transported to the liver. The liver uses these amino-acids to synthesize new proteins, most of which are plasma proteins. The liver also distributes free amino-acids to other tissues, for synthesis of tissue-specific proteins. Proteins are synthesized based on genetic information of the cell, using the genetic code, and regulatory signals. Each cell has a characteristic collection of proteins, specific to its functions.
Body proteins are constantly renewed. Older proteins are broken down into free amino-acids, which are recycled, they combine with dietary amino-acids to make new proteins.
Unlike carbohydrates and lipids, proteins cannot be stored for later use. Once the cellular requirement for proteins is met, excess amino-acids are degraded and used for energy, or converted into glucose or fatty acids. Use of amino-acids for energy production also occurs when there is energy shortage, such as during prolonged exercise or extended fasting.
Since there are no nitrogenous compounds in the energy production pathways, the first step in amino-acid degradation is the removal of the amino group, by deamination or transamination, to produce keto-acids. Some amino-acids can be directly deaminated, while others must transfer their amino group to α-ketoglutarate to form glutamate, which is then deaminated to recycle α-ketoglutarate.
Depending on their side chains, keto-acids from different amino-acids may enter the metabolic cycles at different points. They may be converted to pyruvate, acetyl-CoA, or one of the intermediates of the citric acid cycle. Some of these reactions are reversible. When amino-acids are in short supply, citric acid intermediates can be aminated to create new amino-acids for protein synthesis.
Deamination produces ammonia, which is toxic if accumulated. The liver converts ammonia to urea to be excreted in urine. Extreme diets that are excessively high in proteins may overwhelm the kidneys with nitrogenous waste and cause renal damage.

Blood glucose regulation involves maintaining blood glucose levels at constant levels in the face of dynamic glucose intake and energy use by the body. Glucose, shown in figure 1 is key in the energy intake of humans. On average this target range is 60-100 mg/dL for an adult although people can be asymptomatic at much more varied levels. In order to maintain this range, there are two main hormones that control blood glucose levels: insulin and glucagon. Insulin is released when there are high amounts of glucose in the bloodstream.
Glucagon is released when there are low levels of glucose in the bloodstream. There are other hormones that affect glucose regulation and are mainly controlled by the sympathetic nervous system. Blood glucose regulation is very important to the maintenance of the human body. The brain doesn’t have any energy storage of its own and as a result needs a constant flow of glucose, using about 120 grams of glucose daily or about 60% of total glucose used by the body at resting state Without proper blood glucose regulation the brain and other organs could starve leading to death.
Role of Insulin-
1) Enhances entry of glucose into cells; 2) Enhances storage of glucose as glycogen or conversion to fatty acids; 3) Enhances synthesis of fatty acids and proteins; 4) Suppresses breakdown of proteins into amino acids, or adipose tissue into free fatty acids.
Role of Glucagon-
1) Enhances the release of glucose from glycogen (glycogenolysis); 2) Enhances synthesis of glucose (gluconeogenesis) from amino acids or fats.

Blood glucose regulation involves maintaining blood glucose levels at constant levels in the face of dynamic glucose intake and energy use by the body. Glucose, shown in figure 1 is key in the energy intake of humans. On average this target range is 60-100 mg/dL for an adult although people can be asymptomatic at much more varied levels. In order to maintain this range, there are two main hormones that control blood glucose levels: insulin and glucagon. Insulin is released when there are high amounts of glucose in the bloodstream.
Glucagon is released when there are low levels of glucose in the bloodstream. There are other hormones that affect glucose regulation and are mainly controlled by the sympathetic nervous system. Blood glucose regulation is very important to the maintenance of the human body. The brain doesn’t have any energy storage of its own and as a result needs a constant flow of glucose, using about 120 grams of glucose daily or about 60% of total glucose used by the body at resting state Without proper blood glucose regulation the brain and other organs could starve leading to death.
Role of Insulin-
1) Enhances entry of glucose into cells; 2) Enhances storage of glucose as glycogen or conversion to fatty acids; 3) Enhances synthesis of fatty acids and proteins; 4) Suppresses breakdown of proteins into amino acids, or adipose tissue into free fatty acids.
Role of Glucagon-
1) Enhances the release of glucose from glycogen (glycogenolysis); 2) Enhances synthesis of glucose (gluconeogenesis) from amino acids or fats.

Normal level
Fasting plasma glucose- 70 to 110 mg/dl
Post meal plasma glucose-110 to 140 mg/dl
Random plasma glucose- 70 to 140 mg/dl
SOURCES OF BLOOD GLUCOSE AND UTILIZATION
Effect of hormones
1. Insulin- lowers blood glucose, increases uptake, promote Glycogenesis and glycolysis, inhibit gluconeogenesis and glycogenolysis
2. Glucagon- increases blood glucose, promote glycogenolysis and gluconeogenesis
3. Epinephrine- increases blood glucose, promote glycogenolysis and gluconeogenesis
4. Growth hormone, cortisol, ACTH, thyroid hormones- increases blood glucose
ROLE OF GLUCAGON AND EPINEPHRINE IN GLUCOSE REGULATION
ROLE OF INSULIN IN GLUCOSE REGULATION
GLUCOSE UTILIZATION IN DIFFERENT STATES
1. In well fed state – dietary glucose is used for glycogen and fat synthesis. All cells utilize glucose as a source of energy.
2. Post absorptive state- in this state source of glucose is by hepatic glycogenolysis and gluconeogenesis to some extent. Source of energy for brain is glucose. Liver and skeletal muscle utilizes fatty acids as a source of energy.
3. Starvation- After 16 to 18 hrs of fast glycogen store get completely Depleted. Gluconeogenesis in liver and kidney is main source of glucose. Brain utilizes glucose and ketone bodies as a fuel.
4. Prolonged starvation- after several days, main source for gluconeogenesis is muscle proteins. Brain completely depends on ketone bodies as a fuel.
Renal threshold- level of plasma glucose beyond which it is excreted in urine (180mg/dl )
Methods of estimation of plasma glucose
1. Glucose oxidase-peroxidase method
2. Hexokinase method
3. By glucometer
Increase/ Decrease in plasma glucose is called as HYPERGLYCEMIA/HYPOGLYCEMIA
