- 1) When a de-coupler such as 2,4-DNP is added to a respiring mitochondrion, which of the following effects on the process of ETC-OP will be true, which will be false. a) Mitochondria no longer reduce O2 to H2 b) Electrons no longer enter the electron transport chain. c) Activity of Complex V (ATP Synthase) is greatly decreased. d) The P/O ratio for FADH2 becomes larger than the P/O ratio for NADH. e) Protons are no longer pumped from the mitochondrial matrix to the intermembrane space. 2) The rate-limiting step in fatty acid synthesis is: a) condensation of acetyl-CoA and malonyl-CoA. b) formation of acetyl-CoA from acetate. c) formation of malonyl-CoA from malonate and coenzyme A. d) the reaction catalyzed by acetyl-CoA carboxylase.arrow_forwardIn the early days of “mitochondriology,” P/O ratios were determined from measurements of volume of O2 taken up by respiring mitochondria and chemical assays for disappearance of inorganic phosphate. Now, however, it is possible to measure P/O ratios simply with a recording oxygen electrode.
