Video Summary:
Transport proteins create a passage for lipid insoluble and larger molecules to cross the biological membrane. They can be pumps, channels or carriers. Pumps use energy from ATP to drive the primary active transport of a substance against its electrochemical gradient. Channels provide continuous passage for passive diffusion down the electrochemical gradient. Diffusion through channels is faster as multiple ions can pass through the channel during each opening. Pores are always open and gated channels switch between open and closed states. Carriers do not provide continuous passage. Movement through them is relat...

Membrane Transport Proteins
A membrane transport protein (or simply transporter) is a membrane protein[1] involved in the movement of ions, small molecules, or macromolecules, such as another protein, across a biological membrane. Transport proteins are integral transmembrane proteins; that is they exist permanently within and span the membrane across which they transport substances. The proteins may assist in the movement of substances by facilitated diffusion or active transport. The two main types of proteins involved in such transport are broadly categorized as either channels or carriers. The solute carriers and atypical SLCs[2] are secondary active or facilitative transporters in humans.[3][4]

A Day in the Life of a Motor Protein
The primary aim of the Hoogenraad research lab at the University of Utrecht, the Netherlands, is to understand how intracellular protein transport underlies the development and function of nerve cells. During this 5 min movie we follow John, a motor protein, who has to transport his package to the right destination in the nerve cell, illustrating the relevance and mechanisms of proper intracellular transport in the nervous system.

Video Summary:
Transport proteins create a passage for lipid insoluble and larger molecules to cross the biological membrane. They can be pumps, channels or carriers. Pumps use energy from ATP to drive the primary active transport of a substance against its electrochemical gradient. Channels provide continuous passage for passive diffusion down the electrochemical gradient. Diffusion through channels is faster as multiple ions can pass through the channel during each opening. Pores are always open and gated channels switch between open and closed states. Carriers do not provide continuous passage. Movement through them is relatively slow. Uniporters move a single type of substance down its concentration gradient. Symporter moves one substance downhill and uses it's energy to move other substance uphill in same direction. Antiporters also move one substance downhill and uses it's energy to move other substance uphill but in opposite direction.

A membrane transport protein (or simply transporter) is a membrane protein[1] involved in the movement of ions, small molecules, or macromolecules, such as another protein, across a biological membrane. Transport proteins are integral transmembrane proteins; that is they exist permanently within and span the membrane across which they transport substances. The proteins may assist in the movement of substances by facilitated diffusion or active transport. The two main types of proteins involved in such transport are broadly categorized as either channels or carriers. The solute carriers and atypical SLCs[2] are secondary active or facilitative transporters in humans.[3][4]

Difference between channels and carriers
A carrier is not open simultaneously to both the extracellular and intracellular environments. Either its inner gate is open, or outer gate is open. In contrast, a channel can be open to both environments at the same time, allowing the molecules to diffuse without interruption. Carriers have binding sites, but pores and channels do not.[5][6][7] When a channel is opened, millions of ions can pass through the membrane per second, but only 100 to 1000 molecules typically pass through a carrier molecule in the same time.[8] Each carrier protein is designed to recognize only one substance or one group of very similar substances. Research has correlated defects in specific carrier proteins with specific diseases.[9]
Active diffusion
Main article: Active transport
The action of the sodium-potassium pump is an example of primary active transport. The two carrier proteins on the left are using ATP to move sodium out of the cell against the concentration gradient. The proteins on the right are using secondary active transport to move potassium into the cell.
Active transport is the movement of a substance across a membrane against its concentration gradient. This is usually to accumulate high concentrations of molecules that a cell needs, such as glucose or amino acids. If the process uses chemical energy, such as adenosine triphosphate (ATP), it is called primary active transport. Secondary active transport involves the use of an electrochemical gradient, and does not use energy produced in the cell.[10] Unlike channel proteins which only transport substances through membranes passively, carrier proteins can transport ions and molecules either passively through facilitated diffusion, or via secondary active transport.[11] A carrier protein is required to move particles from areas of low concentration to areas of high concentration. These carrier proteins have receptors that bind to a specific molecule (substrate) needing transport. The molecule or ion to be transported (the substrate) must first bind at a binding site at the carrier molecule, with a certain binding affinity. Following binding, and while the binding site is facing the same way, the carrier will capture or occlude (take in and retain) the substrate within its molecular structure and cause an internal translocation so that the opening in the protein now faces the other side of the plasma membrane.[12] The carrier protein substrate is released at that site, according to its binding affinity there.

The primary aim of the Hoogenraad research lab at the University of Utrecht, the Netherlands, is to understand how intracellular protein transport underlies the development and function of nerve cells. During this 5 min movie we follow John, a motor protein, who has to transport his package to the right destination in the nerve cell, illustrating the relevance and mechanisms of proper intracellular transport in the nervous system.

The video depicts a kinesin motor protein pulling a vesicle full of cargo, such as proteins, across a microtubule filament. Eukaryotic cells contain many membrane-bound organelles, such as the Golgi apparatus, which the vesicles recognize with their membrane proteins and fuse into the target organelle's membrane.

Welcome to the Brahmastra Series! Join us for a comprehensive session on CSIR NET Unit 1: Molecules and their Interaction Relevant to Biology with the highly esteemed Urmimala Mam. This session is designed to provide you with a deep understanding of the molecular foundations of biology, crucial for excelling in the CSIR NET exam.
🔍 What We Will Cover:
Biomolecules: Structure and function of carbohydrates, lipids, proteins, and nucleic acids.
Enzyme Kinetics: Mechanisms of enzyme action, Michaelis-Menten kinetics, and enzyme inhibition.
Bioenergetics: Concepts of thermodynamics in biological systems, ATP, and energy cycles.
Molecular Interactions: Types of chemical bonds and interactions, hydrophobic, hydrophilic, and Van der Waals forces.
Signal Transduction: Mechanisms of cell signaling and receptor-ligand interactions.
📝 Interactive Q&A:
Got questions or doubts? Urmimala Mam will be answering them live! This is your chance to clarify any uncertainties. Submit your questions in the chat, and we’ll address them during the session.
