1. All the following statements about mitochondria are true except: A. protons are concentrated in the mitochondrial matrix. B. the inner membrane contains proteins for the electron transport chain. C. ATP is produced in the mitochondrial matrix. D. ATP synthase allows the proton gradient to dissipate. E. pyruvate is found in the mitochondria.

Which of the following is TRUE about mitochondrion? ATP Synthase is located in the outer mitochondrial membrane. ATP synthase pumps Na+ and K+ across the mitochondrial membrane to power the electron transport chain. The electrochemical gradient of Na+ across the mitochondrial membrane drives the generation of ATP. The pH in mitochondrial matrix is higher than that in cytoplasm.

1. 2,4-Dinitrophenol (DNP) is a molecule that can shuttle protons across cellular membranes and was used in diet pills in the 1930s (but was quickly discontinued for its lethality). Explain how this molecule might induce weight loss, and why its consumption is often fatal. 2. Biosynthesis and breakdown of glucose share many common enzymes and reactions, but this is not the case in the metabolism of fatty acids. Compare and contrast fatty acid biosynthesis vs. beta-oxidation (location, acyl group carriers,...
