DNP Dinitrophenol is a compound that allows hydrogen ions to leak across a membrane. This leakage prevents the maintenance of an H+ gradient. How would this impact a cell? explain
A. It would permit a greater growth rate, since the cell would no longer have to spend energy pumping H+ across the membrane.
B. It would permit a greater growth rate, because the equalization of H+ on both sides of a membrane would help the cell cope with an acidic environment.
C. If the cell were a neuron, it would have no impact, because the charge differential on the surface of the neuron membrane is based on Na+ and K+, not on H+.
D. The cell would lose the bulk of its energy production because of DNP%u2019s interference with chemiosmosis.
E. It would slow the growth rate slightly, but the cell would compensate by maintaining the function of proton pumps.
