Answer: The ATP(Adenosine Triphosphate) that will be generated if one pyruvate molecule is carried through cellular respiration is 36.
Explanation: Pyruvate is formed through glycolysis cycle which breaks down glucose. The pyruvate is used in aerobic cellular respiration via the TCA cycle yielding 2 ATPs and the electron transport system yielding 34 ATPs. That makes it up to a total of 36 ATPs.
