प्रश्न
What are the main steps in aerobic respiration? Where does it take place?
Advertisements
उत्तर
- Aerobic respiration is a stepwise catabolic process that uses oxygen as the final oxidant and enzymatic regulation to release energy during the complete oxidation of organic food into carbon dioxide and water.
- There are two pathways by which it can occur: the pentose phosphate pathway and the common pathway.
- The first step of the common pathway is called glycolysis because it is shared by anaerobic and aerobic modes of respiration.
- The common pathway of aerobic respiration consists of glycolysis, terminal oxidation, and the Krebs cycle. Within mitochondria, aerobic respiration takes place.
- The final byproduct of glycolysis, pyruvate, is transported from the cytoplasm into the mitochondria.
