question 42
a resting membrane of a muscle cell has an overall electric charge that is
__________ on the inside.
a positive, negative
b positive, positive
c negative, negative
d negative, positive

Explanation:

When a muscle cell is at rest, there is a resting membrane potential. Due to the distribution of ions (such as more \(K^{+}\) inside and more \(Na^{+}\) outside, along with the presence of large negatively - charged intracellular proteins), the inside of the cell membrane is negatively charged and the outside is positively charged.

Answer:

D. negative, positive
