Question

what role does cellular respiration play in the carbon cycle? it removes co₂ from the atmosphere during glycolysis. it removes co₂ from the atmosphere during the citric acid cycle. it releases co₂ to the atmosphere during acetyl coa formation. it releases co₂ to the atmosphere during electron transport.

Explanation:

Cellular respiration releases carbon - containing compounds as CO₂. During the formation of acetyl - CoA from pyruvate, one carbon atom from pyruvate is released as CO₂ into the atmosphere. Glycolysis does not remove CO₂ from the atmosphere. The citric acid cycle releases CO₂, not removes it from the atmosphere. Electron transport does not directly release CO₂; it is mainly involved in generating ATP through the movement of electrons and protons.

Answer:

It releases CO₂ to the atmosphere during acetyl CoA formation.
