Phosphofructokinase is a catalytic enzyme that plays a crucial role in controlling biochemical process. It plays an important role during glycolysis, in converting fructose-6-phosphate into fructose 1,6-biphosphate. It also converts ATP (adenosine triphosphate) into ADP (adenosine diphosphate) molecules. These steps help in controlling the glycolytic pathway.

Question

Which of the following statements is NOT true about the electron transport chain (ETC) and oxidative phosphorylation? A. Oxidative phosphorylation requires the enzyme complexes to be soluble in the mitochondrial matrix. B. If the proton gradient is too high, electrons will not move through the ETC. C. The movement of electrons down the ETC only happens if protons are pumped out of the mitochondrial matrix. D. Oxidative phosphorylation requires the mitochondrial intermembrane space to be more positively charged than the matrix. E. The free energy of the proton gradient can be used to create high energy bonds.
