Multiple Choice
The compound 2,4-dinitrophenol (DNP) is a lipid soluble compound that has been used as a weight loss agent.It functions this way by causing the inner mitochondrial membrane to become leaky with respect to protons.Which result might be expected if cells treated with DNP were examined in detail?
A) The rate of oxygen consumption would be slower in these cells than in untreated cells.
B) The ratio of ATP produced to glucose oxidized would be greater in these cells than in untreated cells.
C) Electron transport in these cells would be completely blocked.
D) ATP production would be slower in these cells than in untreated cells.
E) The pH difference across the mitochondrial inner membrane would be greater in these cells than in untreated cells.
