- Please answer both questions: 1) The sodium-potassium pump: a) equalizes the charge distribution across the cell membrane. b) transports K+ into the cell where it is in high concentration. c) requires very little energy expenditure on the part of nerve cells. d) establishes concentration gradients across the cell membrane. 2) Membrane potentials are always expressed comparing the inside of the cell relative to the outside of the cell. The resting membrane potential is -70 mV because the inside of the cell accumulates ions with negative charges. a) True b) Falsearrow_forwardWhen the kidneys filter plasma, the filtered glucose is reabsorbed from the renal tubules and is not passed in the urine. However, glucose can appear in the urine when the blood sugar is exceptionally high.
