question 2 of 10
which substance is a main product of cellular respiration that is made by the krebs cycle?
a. pyruvate ions
b. water
c. carbon dioxide
d. ethanol

Explanation:

The Krebs cycle, also known as the citric - acid cycle, is a part of cellular respiration. During the Krebs cycle, carbon atoms from acetyl - CoA are released as carbon dioxide. Pyruvate ions are produced in glycolysis, water is produced in the electron - transport chain, and ethanol is a product of fermentation, not the Krebs cycle.

Answer:

C. Carbon dioxide
