Answer:
Krebs cycle and electron transport chain
Explanation:
Energy in form of ATP, which is needed by all living cells, is produced from a cell process called CELLULAR RESPIRATION. Cellular respiration is composed of three other processes depending on the availability of oxygen: glycolysis, Krebs cycle and electron transport chain.
Overall, glycolysis which takes place in the cytoplasm produces 2 molecules of ATP while the Krebs cycle and electron transport chain (ETC) produces a collective accumulation of 34 ATP molecules.
