In this article we will discuss about:- 1. Meaning of Fermentation 2. Types of Fermentation 3. Efficiency. Meaning of Fermentation: The mechanism of anaerobic respiration or fermentation is similar to common pathway of aerobic respiration upto glycolysis. However, oxidation of pyruvic acid and NADH by mitochondria requires oxygen. When oxygen is limiting, NADH and pyruvic acid begin to accumulate. Under [...]
In this article we will discuss about:- 1. Meaning of Pentose Phosphate Pathway (PPP) 2. Reactions of Pentose Phosphate Pathway (PPP) 3. Significance. Meaning of Pentose Phosphate Pathway (PPP): Major pathway for aerobic respiration of glucose is through glycolysis and Krebs cycle, however, an alternate pathway exists in many organisms. This pathway, which requires the presence of oxygen, is called [...]
