4. The electron transport chain also known as the electron transport system, assists in the production of the largest amount of ATP

Answer 2

Breaking down of glucose into pyruvate takes place in Mitochondria of a cell. 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
