describe various paths of glucose breakdown in organism? |
|
Answer» Glycolysis. Glycolysis is the process of breaking down aglucosemolecule into two pyruvate molecules, while storing energy released during this process as ATP and NADH. Nearlyall organisms thatbreak down glucoseutilize glycolysis. ... During the first phase, it requires thebreakdownof two ATP molecules Breaking down of glucose can occur by various pathways ; ⑴ In presence of oxygen : - Breaking down of glucose into pyruvate takes place in Mitochondria of a cell.- End products are CO₂ , H₂O and energy. ⑵ In insufficient presence of oxygen :- In muscle cells, due to insufficient presence of oxygen the cells undergoes anaerobic respiration.- End products are Lactic acid and lot amount of energy. ⑶ In absence of Oxygen :- In absence of Oxygen, glucose breakdown into pyruvate in cytoplasm only.- End product are Ethanol, and small amount of energy. please like my answer if you find it useful |
