a-true
b-false

Answer 1

The sodium channels in nerve conduction have only two conformations: open or closed.

Step-by-step explanation:

The sodium channels in nerve conduction have only two conformations, open or closed.

This statement is true. In the context of nerve conduction, sodium channels exist in two states: open or closed. When a nerve impulse is generated, the sodium channels open, allowing sodium ions to enter the cell and depolarize the membrane. Once enough sodium ions have entered, the channels close again.
