Which of the following are reactants in the process of aerobic respiration?
a.
glucose and water
b.
carbon dioxide and water
c.
glucose and oxygen
d.
carbon dioxide and oxygen

Glucose and oxygen are the reactants of the aerobic respiration. The aerobic respiration is required for the production of energy in the form of energy.

Further Explanation:

Cellular respiration or aerobic respiration is the process by which energy is produced in the form of ATP (adenosine triphosphate). It occurs in three steps, namely; glycolysis, citric acid cycle and electron transport chain.

Glycolysis: in this cycle, the glucose is broken down into a smaller substance called pyruvate in the absence of oxygen. It occurs in the cytoplasm of the cell. Citric acid cycle: In the citric acid cycle, the three-carbon pyruvic acid molecules produced during the glycolysis cycle are decarboxylated. The two carbon molecules from acetyl CoA enters the cycle. This reaction occurs in a closed-loop, including eight steps. Electron transport chain: The electron transport chain is a sequence of proteins and other molecules present in the inner membrane of the mitochondria. The transfer of electrons occurs in a chain of a redox reaction. The energy formed during the reaction is stored in the form of a protein gradient. This protein gradient is used in the formation of ATP by the process called chemiosmosis. The combination of ETC and chemiosmosis is called oxidative phosphorylation.

Oxygen and glucose are the reactants. Oxygen enters the body through breathing, and glucose is obtained from food. Glucose is the substrate that is broken down into water and carbon dioxide in the presence of oxygen. So, carbon dioxide and water are the products. The metabolism of one molecule of glucose will result in thirty-six to thirty-eight molecules of ATP
