ANS:

It produces directly 2 molecules of lactic acid

  • Each cycle of anaerobic glycolysis produces 2 molecules of lactate (lactic acid) whereas in aerobic condition it produces 2 molecules of pyruvate.
  • Option b is tricky one. Each glycolytic cycle produces 4 ATPs (not 2 ATPs). But out of these 4 ATPs, 2 are used in the cycle itself. Therefore, there is net gain of 2 ATPs. So,:-
  1. Each cycle of glycolysis produces4 ATPs.
  2. Each cycle utilizes2 ATPs
  3. Net gain in each cycle2 ATPs
  4. About other options
  5. Hexokinase utilizes ATP (not produces ATP).
  6. Aldolase produces reversible isomerization.
