Which diagram in the figure above shows a voltage-gated channel? Select one: a. A b. B c. C d. D e. None of the above

Solution

Answer: A: voltage gated channel. Here change in the membrane potential opens the gate. These are transmembrane proteins which form ion channels which are activated when there is change in the electrical potential of the membrane near the ion channel.

B: pressure or stretch gated channel

C: phosphorylation gated channel

D: ligand gated channel
