  • 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?
