Question

Distinguish between glycolysis and Krebs cycle.

Answer 1

	Glycolysis	Krebs cycle
1	It is a linear pathway.	It is a cyclic pathway.
2	It occurs in the cell cytoplasm.	It occurs in the mitochondrial matrix.
3	It occurs in both aerobic as well as anaerobic respiration.	It occurs in aerobic respiration only.
4	The glucose molecules are broken down into two pyruvate molecules along with the productionof 8 ATP.	It produces 15 ATP during the interconversion of one pyruvate molecule. Two pyruvate molecules are formed by one molecule of glucose so two molecules of kerb's cycle are needed to process the pyruvates. So, total 30ATP (15 *2) is produced.
