Reuptake of acetylcholine, animation
Videonummer 11935710
| Reuptake of acetylcholine. Animation showing the reuptake of acetylcholine by an antiport pump driven by ATP hydrolysis. In the brain, nerve cells use an electric membrane potential to pass information onto postsynaptic cells. This action potential reaches the end of the nerve cell and causes the release of a neurotransmitter which works to pass this potential onto the postsynaptic cell. Once the signal has been successfully passed on, the neurotransmitter is subject to reuptake and re-enters the presynaptic cell. Here, the membrane protein responsible for the reuptake of the neurotransmitter acetylcholine is shown in action and protons (blue) are exchanged for acetylcholine (yellow and green). The image to the bottom left shows a more detailed picture of this protein on the surface of a vesicle. | |
