Carbon dioxide is returned to the atmosphere primarily by respiration of humans, (exhalation to be precise). The return of carbon dioxide to the atmosphere is also possible by the decay of plants and animals and combustion, which is the process of burning something.
Answer:
2.it has gained extra electron
Answer:
The correct answer is a. energy can be extracted in usable amounts.
Explanation:
Through the process of respiration, glucose is converted into carbon dioxide and water. This oxidation of glucose helps in the production of energy in usable amount which is used by the cell for their metabolic processes.
First, the glucose is partially oxidized to pyruvic acid then pyruvic acid is converted into acetyl Co-A which is used in the citric acid cycle to generate NADH, FADH₂, and ATP. Then the NADH, FADH₂ is used to provide electrons that helps in the generation of ATP through oxidative phosphorylation.
This ATP molecule has a high energy phosphate bond from which energy can be extracted in usable amounts. Therefore the correct answer is a. energy can be extracted in usable amounts.
