12) Water passes quickly through cell membranes because
13) Among enzymes, kinases catalyze phosphorylation, while phosphatases catalyze removal of phosphate(s). A cell's use of these enzymes can therefore function as an on - off switch for various processes. Which of the following is probably involved?

15) What is the most important factor in explaining why diffusion occurs spontaneously? A) It has a high energy of activation B) It is endothermic. C) It leads to a decrease in entropy. D) It leads to an increase in entropy.
16) Phosphofructokinase is an allosteric enzyme that catalyzes the conversion of fructose - 6 - phosphate to fructose - 1,6 - bisphosphate, an early step of glycolysis. In the presence of oxygen, an increase in the amount ATP in a cell would be expected to
