Q1 · Respiration in Plants · EASY
During glycolysis, one molecule of glucose is broken down into two molecules of pyruvic acid with a net gain of how many ATP molecules?
Q2 · Respiration in Plants · MEDIUM
The respiratory quotient (RQ) for carbohydrates is 1. What would be the RQ value when fats are used as respiratory substrate?
Q3 · Respiration in Plants · MEDIUM
In the Krebs cycle, succinyl-CoA is converted to succinate. This reaction is coupled with the synthesis of which high-energy molecule?
Q4 · Respiration in Plants · MEDIUM
During alcoholic fermentation in yeast, pyruvic acid is first decarboxylated to form acetaldehyde. Which enzyme catalyzes this irreversible step?
Q5 · Respiration in Plants · HARD
In the electron transport chain (ETC), the final electron acceptor in aerobic respiration is molecular oxygen. If the passage of electrons through Complex I, III, and IV generates a total of 10 H+ ions pumped into the intermembrane space per NADH, and approximately 3 H+ are needed to synthesize 1 ATP via ATP synthase, approximately how many ATP molecules are generated per NADH oxidized?
