Verified Answer :

Final answer:

The reactant of cellular respiration from your choices is oxygen. Cellular respiration involves oxygen and glucose as reactants, which produce carbon dioxide and water along with energy. Therefore, the correct response to your question is oxygen.


Explanation:

Understanding Cellular Respiration


Cellular respiration is a biological process through which organisms convert nutrients into energy. This process primarily occurs in the mitochondria of cells. To identify a reactant of cellular respiration, let's look at the main components involved in this chemical reaction.

Reactants of Cellular Respiration


The main reactants of cellular respiration are:



  1. Oxygen

  2. Glucose (not listed in your choices)


When these reactants combine in the presence of enzymes, they undergo a series of reactions that produce products like carbon dioxide and water, along with energy in the form of ATP.

Choices Analysis


From your provided choices:



  • Carbon dioxide: This is a product, not a reactant, of cellular respiration.

  • Water: This is also a product formed during the process.

  • Oxygen: This is a correct reactant for cellular respiration.

  • Energy: This is a product, not a reactant.


Thus, the only correct answer to your question is oxygen.
