Question

What is the correct sequence of stages in the metabolic pathway of cellular respiration?

glycolysis, electron transport chain, citric acid cycle

glycolysis, citric acid cycle, electron transport chain

citric acid cycle, glycolysis, electron transport chain

citric acid cycle, electron transport chain, glycolysis

Answer 1

B.) glycoloysus, citric acid cycle, and then electron transport chain

Answer 2

Glycolysis, citric acid cycle, electron transport chain

Step-by-step explanation:

Cellular respiration is the process of oxidation of nutrients in step wise manner to retrieve energy from them. It has three stages: glycolysis, citric acid cycle, electron transport chain

a) Glycolysis: The first stage of cellular respiration that breaks down the glucose into pyruvate and occurs in cytoplasm

b) Kreb's cycle or citric acid cycle: Pyruvate enter Kreb's cycle in form of acetyl CoA and is completely broken down into carbon dioxide and water.

c) Electron transport chain: the final step of cellular respiration that oxidized NADH and FADH2 formed during glycolysis and Kreb's cycle.
