Write steps for process of anaerobic respiration
Answers
The cells of most living things make ATP from glucose in the process of cellular respiration. This process occurs in three stages: glycolysis, the Krebs cycle, and electron transport. The latter two stages require oxygen, making cellular respiration anaerobic process.
Aerobic respiration occurs in main four steps, namely glycolysis, link reaction, Krebs cycle and terminal oxidation.
Glycolosis: It is partial oxidation of glucose to form two molecules of pyruvate, two NADH, and two ATP. Glycolysis occurs in the cytoplasm.
Link Reaction: After entering mitochondria, pyruvate undergoes oxidative decarboxylation to form acetyl CoA and NADH. CO is released.
Krebs Cycle: Acetyl CoA reacts with oxaloacetate. The product, citrate, undergoes two oxidative decarboxylations and two dehydrogenations. Oxaloacetate is regenerated. The byproducts are 3 NADH, 1 FADH, 1 ATP or GTP and 2CO. Krebs Cycle occurs inside mitochondria.
Terminal Oxidation: NADH and FADH are oxidized. The energy liberated during oxidation is used in the synthesis of ATP and ADP and inorganic phosphate. Hydrogen is ultimately oxidized by oxygen to form water. Terminal oxidation takes place over the inner membrane of mitochondria.
