Products are what is created during a reaction. What are the three products of cellular respiration
Setler79 [48]

Answer:

The three products of cellular respiration are:

  1. ATP
  2. Water
  3. Carbon dioxide

Explanation:

  • Cellular respiration is the process of breaking down glucose molecules to yield energy in the form of ATP.
  • C6H12O6 + 6O2 → 6CO2 + 6H2O

ATP Production:

  • The first step of cellular respiration, glycolysis, yields 2 net ATP.
  • The second step, Kreb's cycle produces 10 NADH and 2 FADH2 molecules. Both these molecules store energy that is released in the electron transport chain to produce 34 ATP.
  • Therefore, a total of 36 ATP are produced as a result of cellular respiration in eukaryotes.

Carbon dioxide Production:

  • 2 molecules of CO2 are produced during the conversion of pyruvate into Acetyl Co-A by the <em>pyruvate dehydrogenase</em> complex.
  • 4 molecules of CO2 are produced in the Kreb's cycle.

Water Production:

  • Water is produced in the Electron Transport Chain (ETC) by the reduction of oxygen.
