1. Differentiate between
(b) Glycolysis and Krebs’ cycle
| Glycolysis | Krebs cycle |
| Glycolysis takes place inside the cytoplasm | It occurs inside mitochondria |
| It is a straight or linear pathway | It is a cyclic process |
| This process is common to both aerobic and anaerobic respiration | This process occurs only in aerobic respiration |
| It breaks down one molecule of glucose into two molecules of pyruvate | It breaks down pyruvate completely into carbon dioxide and water |
| It consumes two ATP molecules | It does not consume ATP |
