Glycolysis is described as anaerobic because it:
AUses no oxygen
BUses no water
CUses no carbon
DUses no enzymes
Answer & Solution
Correct answer: A. Uses no oxygen
1. Aerobic and anaerobic describe whether a pathway needs oxygen.
2. Glycolysis runs in the cytoplasm without any oxygen present.
3. The process does not use oxygen and is therefore anaerobic.
4. It certainly uses enzymes and water, so those options misread the term.
