Sri K.
A sodium-potassium antiport maintains the extracellular concentration of sodium at levels that are about 20-30 times higher than inside the cells. What directly supplies the energy for maintaining this gradient? Select one: a. Potassium supplies the energy, as it is moving along its concentration gradient. b. Sodium supplies the energy, as it is moving along its concentration gradient. c. ATP hydrolysis drives the function of the pump. d. A proton gradient in the mitochondria drives the antiport. (Q008) Which of the following ions has a low cytosolic concentration so that a flood of this ion into the cell can be used as a signal for cell processes like fertilization? Select one: a. Ca2+ b. H+ c. K+ d. phosphate
