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

Cellular respiration is the process by which organic sugars are broken down to produce energy. It plays a vital role in the carbon cycle because it releases carbon dioxide into the atmosphere. This means that cellular respiration can be thought of as the opposite of carbon fixation in the carbon cycle.

The correct answer is option C. it releases the CO2 to the atmosphere during acetyl CoA formation.

Explanation:

Acetyl CoA formation takes place in the oxidative decarboxylation of pyruvate decarboxylation or link reaction which is an intermediate stage of cellular respiration that oxidizes pyruvate molecule to the acetyl CoA which also releases carbon dioxide in this process to the atmosphere.

The formation of acetyl CoA releases the carbon dioxide to the atmosphere during link reaction, however, the release of carbon dioxide also takes place during Kreb's cycle.

Thus, the correct answer is option C.  it releases the CO2 to the atmosphere during acetyl CoA formation.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
