________________ are reactants in the process of cell respiration.
A) Water and sugar
B) Sugar and oxygen
C) Water and oxygen
D) Water and carbon dioxide

Respuesta :

Answer: The correct answer for the blank is-

B) Sugar and oxygen.

Explanation:

Cellular respiration can be described a metabolic process that includes the break down of organic molecule like glucose (a carbohydrate or sugar) to form carbon dioxide and water along with large amount of energy in the form of ATP ( adenosine triphosphates), which is used for driving various cellular processes.

Aerobic cellular respiration involves the presence of oxygen along with glucose.

Thus, sugar and oxygen, being the reactants in cellular respiration is the right answer.

Sugar and oxygen are the reactants of the cell respiration.

Further Explanation:

Cellular respiration or cell respiration occurs in the living cells. It is the process by which energy is produced in the form of ATP (adenosine triphosphate). It provides energy for the metabolic activity of the cell. It involves a series of chemical reactions, namely; glycolysis (the breakdown of glucose), citric acid cycle and electron transport chain.

Oxygen and glucose (sugar) are the reactants that undergo a metabolic reaction to produce energy. Oxygen enters the body through breathing and glucose is obtained from food. Glucose is the complex substrate which is broken down into water and carbon dioxide in the presence of oxygen. So, carbon dioxide and water are the products.

During cellular respiration, one glucose molecule reacts with six oxygen molecules that yield six molecules of carbon dioxide and water. During the process, ATP is generated. The breakdown or metabolism of glucose(one molecule) will result in thirty-six to thirty-eight molecules of ATP.
