  • What is the net ATP gain from glycolysis?
    The net ATP gain is 2 ATP molecules, since 2 ATP are invested and 4 ATP are produced.
  • How many NADH molecules are produced during glycolysis?
    Glycolysis produces 2 NADH molecules per glucose molecule.
  • Does glycolysis release any carbon dioxide?
    No, glycolysis does not release any carbon dioxide.
  • Which reactions in Phase A of glycolysis are irreversible?
    Reactions 1 and 3 in Phase A are irreversible.
  • What is the main product of glycolysis?
    The main product is pyruvate, with 2 pyruvate molecules formed per glucose.
  • What is the memory tool for remembering Phase A reactions?
    The memory tool is 'I irresponsibly ate 1 third of a pizza.'
  • Which enzyme class catalyzes phosphorylation reactions in glycolysis?
    Kinases catalyze phosphorylation reactions, such as in reactions 1 and 3.
  • What is the memory tool for Phase B reactions of glycolysis?
    The memory tool is 'green peas in a baked potato gratin.'
