Let us make an in-depth study of the four stages involved in the aerobic respiration process. The four stages involved in the aerobic respiration process are: (1) Glycolysis (or EMP-Pathway of Glycolytic Breakdown) (2) Pyruvate Oxidation or Conversion of Pyruvic Acid to Acetyle Coenzyme A (3) TCA Cycle or Krebs’ Cycle and (4) Terminal Oxidation. Stage I of Respiration: Glycolysis [...]
The below mentioned article provides a note on fat respiration and protein respiration. (i) Fat Respiration: Fats are stored as triglycerides in cells, primarily of adipose tissue. They have a high energy content, and form a better fuel than the carbohydrates. They break up into fatty acids and glycerol in the cytoplasm before use in respiration. Fatty Acids: Fatty acids [...]
Let us make an in-depth study of the anaerobic respiration. As the reactions of glycolysis do not require oxygen, pyruvic acid is formed as in aerobic respiration. When sufficient oxygen is not available, the citric acid cycle and ETS cannot operate. Under such conditions metabolism of pyruvic acid may proceed anaerobically (i.e., without oxygen). As the reactions of glycolysis do [...]
