Aerobic Respiration
Question
The number of ATP molecules formed by substrate level phosphorylation in glycolysis and krebs cycle during complete aerobic oxidation of one molecule of glucose is
Easy
Solution
In glycolysis,
2(1,3-bisphoglyceric acid → 3-phosphoglyceric acid) and 2(Phosphoenol pyruvate → Pyruvate) produces 2 ATP each. Therefore, total number of ATP produced by substrate level phosphorylation is 4 ATP.
In Krebs cycle
Succinyl CoA→ Succinic acid. Then ATP or GTP is produced. Krebs cycle occurs twice for 1 glucose molecule. Therefore, 2ATPs are produced.
