What role does cellular respiration play in the carbon cycle?

Question

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.

Answer 1

Cellular respiration plays a role in the carbon cycle by releasing CO2 to the atmosphere during the citric acid cycle, acetyl CoA formation, and electron transport. While glycolysis does not directly remove CO2 from the atmosphere, it is the first step in the process of cellular respiration and ultimately leads to the release of CO2 during the citric acid cycle and subsequent steps. Therefore, both the second and fourth options are correct.
