Which correctly lists the order of aerobic respiration from step one to step three?

The correct answer is option C. glycolysis, citric acid cycle and electron transport chain.

Explanation:

Aerobic respiration is a set of chemical reactions in which energy transfers to cells. Carbon dioxide and water are waste products in this process. It is called aerobic respiration because this process uses oxygen. It has 3 main stages known as glycolysis, the Krebs cycle or citric acid cycle, and the electron transport chain, it takes place in this order only.

Several enzymes in several steps split a glucose molecule into 2 molecules of pyruvate during glycolysis, and produce ATP molecules.

The 3rd carbon from pyruvate combines with an oxygen molecule to make carbon dioxide, which is a waste product in this reaction.

The main purpose of the electron transport chain is to build up a gradient of H⁺ ions in the intermembrane space so that there will be a concentration gradient the matrix of the mitochondria.

Thus, the correct answer is option C.
