Answer 1

Answer: none

Explanation:

The resting membrane potential is determined by the uneven distribution of ions (charged particles) between the inside and the outside of the cell, and by the different permeability of the membrane to different types of ions.

Answer 2

The resting potential membrane is determined by

The resting potential membrane is determined byPotassium-ion gradient so the correct option is (A) potassium ion gradient.

• The resting potential is expected mainly due to two factors: the elevated concentration of potassium ions in the intracellular fluid and the increased permeability of the cell membrane to potassium ions related to other ions.
• K+ activity is the fundamental determinant of the resting potential. It is form in much higher concentrations inside the cell 150mM than outside the cell 5mM.
