-What is occurring in Step 2 of Figure 8.1, and how is that process originated?
A) remove neurotransmitter from the synaptic cleft : reuptake
B) receptor that can stimulate a cellular response by gating its ion channel : stimulating a G protein to gate an ion channel
C) fast receptor opens an ion channel that is part of the receptor : reuptake
D) influx of calcium : depolarization causes voltage -gated calcium channels to open
E) slow receptor can open or close an ion channel by G protein coupling between receptor and ion channel : neurotransmitter release

Quizplus · Accepted Answer

In Step 2 of Figure 8.1, the influx of calcium into the cell is typically caused by depolarization, which triggers voltage-gated calcium channels to open. This process is crucial for various cellular activities, including neurotransmitter release in neurons.
