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

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.
