Exercise 4

Mitochondrial Transport. For aerobic respiration, a variety of substances must be in a state of flux across the inner mitochondrial membrane. Assuming a brain cell in which glucose is the sole energy source, indicate for each of the following substances whether you would expect a net flux across the membrane and, if so, how many molecules will move in which direction per molecule of glucose catabolized.
(a)Pyruvate
(b)Oxygen
(c)ATP
(d)ADP
(e)Acetyl CoA
(f)Glycerol-3-phosphate
(g)NADH
(h)FADH2
(i)Oxaloacetate
(j)Water
(k)Electrons
(l)Protons
