question 76

Multiple Choice

Two fundamental principles that characterize gated ion channels in the neuronal membrane are that the channels

• A) are always open, but the concentration gradients of ions frequently change.
• B) are always closed, but ions move closer to the channels during excitation.
• C) open and close depending on stimuli and are specific as to which ion can traverse them.
• D) open and close depending on chemical messengers and are nonspecific as to which ion can traverse them.
• E) open in response to stimuli and then close simultaneously, in unison.
