Ion channels
In this 3d video I made on blender, I show you the different types of ion channels found in the plasma membrane of a neuron and that allow the exchange of ions from the extracellular medium to the intracellular one and vice versa: 3 types are shown, some needs energy to function well ..
I hope you like it. thanks in advance.

Transport Proteins: Pumps, Channels, Carriers

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...

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.

All animal cells are enclosed in a plasma membrane, which consists of 2 layers of phospholipids. The hydrophobic nature of the cell membrane makes it intrinsically permeable to small NON-polar and uncharged polar molecules, but NON-permeable to large polar molecules and CHARGED particles. Charged particles, such as ions, must use special channels to move through the membrane.
Transport of a molecule can be passive or active. PASSIVE transport does NOT require energy input because it moves the molecules “DOWNHILL”, for example, from HIGHER to LOWER concentration. ACTIVE transport, on the other hand, moves the molecules AGAINST their gradients and therefore requires ENERGY expenditure.
Ion channels permit PASSIVE transport of ions. These are transmembrane proteins that form PORES for ions to pass through. Most ion channels are SPECIFIC for a certain type of ion.
Ion channels can be classified by how they change their OPEN-CLOSED state in RESPONSE to different factors of the environment. Common types of ion channels include:
- LEAK channels: these channels are almost always OPEN allowing more or less steady flow of ions; examples are potassium and sodium leak channels in neurons.
- LIGAND-gated ion channels: these channels OPEN upon BINDING of a LIGAND. They are most commonly found at synapses, where neurons communicate via chemical messages, or neurotransmitters. An example is the GABA receptor, a chloride channel located on POST-synaptic neurons. It OPENS upon binding to GABA, a neurotransmitter released by the PRE-synaptic neuron, and allows chloride ions to flow into the cell.
- VOLTAGE-gated ion channels: these channels are REGULATED by membrane voltage. They OPEN at some values of the membrane potential and CLOSE at others. These are the channels that underlie ACTION POTENTIALS in neurons and cardiac muscles.
ACTIVE transport of ions is carried out by ion transporters, or ion PUMPS. These are transmembrane proteins that PUMP ions AGAINST their concentration gradient using cellular ENERGY, such as ATP. Most notable example is the sodium-potassium pump which maintains the resting potential in neurons by pumping two potassium IN and three sodium OUT of the cell.
Another type of ion transporters, known as SECONDARY transporters, do NOT use ATP directly. Instead, they move ONE ion DOWN its concentration gradient and use THAT ENERGY to POWER the transport of a SECOND ion. Symporters transport the two ions in the same direction, while antiporters pump the coupled molecule in the OPPOSITE direction.
