Or (a) Briefly discuss the different pathways of energyproduction by oxidation of glucose in differentorganisms |
|
Answer» After conversion of glucose into pyruvate , energy can be released by any of the 3 pathways .1. Aerobic respiration - Pyruvate is oxidized in the presence of enough oxygen to release water, carbon dioxide and energy in the form of 38 ATPs. This process is conducted in mitochondria.2. Anaerobic respiration - energy is released in the presence of less amount of oxygen then required. The end products are 2ATPs and lactic acid.3 .Fermentation-This pathway is followed by yeast to respire. Energy is released in the absence of oxygen. The end products are energy, carbon dioxide and water. |
