Question

All organisms perform _____, whether or not oxygen is present.

A). Glycolysis
B). Aerobic respiration
C). Photosynthesis
D). None of the above

Answer 1

Answer: Glycolysis

Step-by-step explanation:

Glycolysis is an universal process which takes place in all the organism from bacteria to humans. It can occur whether oxygen is present or not. It is the first step of cellular respiration that takes place in cytosol.

During glycolysis, breakdown of the glucose into pyruvate occurs with the formation of two energy molecules of ATP and two NADH molecules.

Thus, the correct answer is option (A).
