A) the inefficiency of glycolysis compared to aerobic respiration.
B) the long period of time that is required before it can start supplying ATP.
C) the rapid rate at which glycolytic enzymes produce ATP.
D) its ability to supply ATP for extended periods of time.
E) its ability to function in the absence of oxygen.

Question

Quizplus · Accepted Answer

C  E  A) Glycolysis is less efficient than aerobic respiration because it produces only 2 ATP molecules per glucose molecule compared to up to 38 ATP in aerobic respiration.  C) Glycolysis can rapidly produce ATP, which is crucial for short bursts of activity.  E) Glycolysis can occur without oxygen, making it an anaerobic process.
