Electron transport chain - Kreb's cycle- glycolysis
Krebs cycle electron - transport-chain glycolysis
Glycolysis - Krebs cycle - electron transport chain
Glycolysis - electron transport chain - Kreb's cycle
Cellular respiration is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. Aerobic respiration, or cell respiration in the presence of oxygen, uses the end product of glycolysis (pyruvate) in the TCA cycle to produce much more energy currency in the form of ATP. After TCA cycle molecules pass through the electron transport chain which produces the necessary proton gradient for ATP synthesis. Hence the correct option is C.
