Question

Q1: All of the following help to set up the resting membrane potential except:

a. plasma membrane being semi-permeable, gates open and close.

b. potassium leak channels.

c. unequal distribution of Na and K inside and outside of cells.

d. anions remain intracellularly.

e. Na/K ATPase pump.

Q2: If one poisoned a skeletal muscle cell and ATP was not able to be made, all would occur except:

a. remain at resting membrane potential permanently.

b. no cross bridge release.

c. no action potential in muscle cell.

d. no active transport of Ca into sarcoplasmic reticulum.

e. no cross bridge formation.

Answer: Option A

Plasma membrane being semi-permeable, gates open and close. and this factor does not contribute much to resting membrane potential
