Answer
Answer:
Glycolysis is the enzymatic breakdown of one molecule of glucose (6-carbon) into two molecules of pyruvic acid (3-carbon each). It occurs in the cytoplasm of the cell and does not require oxygen, making it common to both aerobic and anaerobic respiration.
Key features:
- Net gain: 2 ATP, 2 NADH + H⁺
- Location: Cytoplasm
- Enzymes: Hexokinase, phosphofructokinase, pyruvate kinase
