Give any three differences between Glycolysis and Krebs cycle.
Glycolysis: It is the first step in respiration. In this step, one molecule of glucose (C6H12O6) is broken down into two molecules of pyruvic acid. This step occurs in the cytoplasm.
Krebs cycle: In this step, each pyruvic acid molecule if first converted into acetyl co-A which is followed by a series of reactions. This step occurs in the mitochondria.
Differences
Glycolysis | Krebs Cycle |
Glycolysis is the first step of respiration which is common in both aerobic and anaerobic respiration. | Krebs cycle is found only in aerobic respiration. |
Glycolysis occurs in the cytoplasm of the cell. | Krebs cycle occurs in the mitochondria of the cell. |
In glycolysis, one molecule of glucose is converted into two molecules of pyruvic acid. | In Krebs cycle, each pyruvic acid is converted into Carbon dioxide and water. |
