Question

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.

Answer 1

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

Answer 2

During cellular respiration, cells released CO2 in the atmosphere during 'acetyl CoA' formation.

Explanation:

During cellular respiration, cell break down glucose molecules into water and carbon dioxide to produce ATP. ATP is the power that a body needs to function. There are '4 stages of cellular respiration' which are Glycolysis, Pyruvate oxidation, Citric-acid cycle and oxidative phosphorylation.

In 'pyruvate oxidation', each pyruvate from the glycolysis goes into mitochondria and it is converted into 'two-carbon molecule' bound to coenzyme A. It is known as CoA. 'Carbon dioxide' is released.
