Answer:
The change in conformation of voltage-gated calcium channels in the axon terminal membrane causes the increase in cytosolic calcium that triggers the fusion of secretory vesicles to the membrane and the release of neurotransmitters into the synaptic cleft.
Explanation:
- As the calcium concentration becomes less in the cytosol, it allows calcium ions and functions it as a secondary messenger in the calcium signaling process.
- During the action potential, or any nerve impulse, that arrives at the terminal of axon, the activation of voltage-gated calcium channel is carried. This activation is done in the cell membrane.
- Calcium ion has the key responsibility for the triggering of synaptic vesicles to release the neurotransmitters.
<span>Correct answer:
<span>Diffusion is the movement of particles from a high to low concentration, while osmosis is the movement of water from a high particle concentration to a low particle concentration.
</span></span><span>This movement of molecules occurs due to a thermal motion. Diffusion normally occurs between two compartments having difference in concentration. In case of fluid it moves from the region of higher concentration to the region of concentration until a balance is reached. The process of diffusion is very important for the humans as well. The oxygen that humans breathe in gets diffused with the blood.</span><span><span>
