In this article we will discuss about the synthesis of ATP formation. In the early 1930s it was clear that the ADP phosphorylation was coupled to respiration. Lehninger and other workers between 1948-51 conducted biochemical studies on isolated mitochondria and tissue samples. From their studies following general inferences emerged: i. Phosphorylation depended upon oxygen. ii. Mitochondria when isolated catalyzed oxygen-dependent [...]
The following points highlight the four major parts of respiration of starch or sugar. The parts are: 1. Glycolysis 2. Krebs or Citric Acid Cycle 3. Anaerobic Oxidation of Pyruvic Acid 4. Fate of Pyruvate under Aerobic Conditions. Part # 1. Glycolysis: The reactions of the EMP pathway of glycolysis are given in Fig. 17-2A, B; 17-3. The process may [...]
The following points highlight the two main types of respiration enzymes. The types are: 1. Non-Oxidative 2. Oxidative. Type # 1. Non-Oxidative: Transphosphorylases: These enzymes catalyze transfer of phosphate group, from one kind of molecule to another, or form one carbon atom to other in the same molecule. The presence of magnesium ions is essential for the activity of some [...]
