Question
Indicate whether the statements below are true or false. If a statements is false, explain why it is false.A. Neurotransmitters are small molecules released into the synaptic cleft after the fusion of synaptic vesicles with the presynaptic membrane.
B. Action potentials are usually mediated by voltage-gated Ca+ channels.
C. Voltage gated Na+ channels become automatically inactivated shortly after opening, which ensures that the action potential cannot move backward along the axon.
D. Voltage-gated K+ channels also open immediately in response to local depolarization, reducing the magnitude of the action potential.
Explanation / Answer
2. A. The given statement is true.
B. The given statement is false- because voltage gated Na2+ channels is the reason for development action potential in an excited cell.
C. The given statement is true.
D. The given statement is true.
