The oxidation of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate is an endergonic reaction, but the flow through this point in glycolysis proceeds smoothly. How is the unfavorable equilibrium constant overcome?
Why is the reaction that is catalyzed by E3 in the oxidative decarboxylation of pyruvate by the pyruvate dehydrogenase complex not involved in the forming of the product (acetyl CoA) but still is important to the process of the complex? Explain why it is important.
In the presence of excess oxygen, a complete oxidation of nine molecules of glucose into carbon dioxide and water, by a yeast cell, would produce approximately __________ ATP molecules via oxidative phosphorylation only.
