What role does Ca²⁺ play in synaptic transmission?
A)Ca²⁺ is released into the synapse,transmitting a signal to the postsynaptic cell.
B)Ca²⁺ causes the release of vesicles from the readily releasable pool.
C)Ca²⁺ causes vesicles to move from the storage pool to docking proteins.
D)both B and C

Question

Quizplus · Accepted Answer

Ca²⁺ plays a crucial role in synaptic transmission by causing the release of vesicles from the readily releasable pool (B) and by causing vesicles to move from the storage pool to docking proteins (C). This ultimately results in the release of neurotransmitters from the presynaptic neuron and their transmission to the postsynaptic neuron.
