Question

How is oxygen important in aerobic respiration?

Answer 1

Respiration mechanism is the process which is used by organisms like eukaryotes and prokaryotes to break down the food and it requires environmental oxygen as it is an important element for the living beings to survive on the earth.

Complete answer:
Cellular respiration is of two types that are aerobic respiration and anaerobic respiration and the type of cellular respiration that takes place in plants, animals, humans, and other microorganisms in aerobic respiration which needs oxygen to facilitate the energy transfer during cellular respiration.

Oxygen plays an important role in aerobic respiration as aerobic means with air and when an electron is harvested then ATP forms and transferred along the electron transport chain and donated to oxygen gas.

Basic photosynthetic machinery is modified and gives aerobic respiration and three dozen ATP molecules are produced in eukaryotes with the oxidation of glucose by aerobic respiration.

Cellular respiration is different from normal respiration as breathing is commonly known as breathing because it involves a physical process of inhaling and exhaling and cellular respiration is the process that takes place inside the cells and involves oxygen for the energy transfer to ATP.

Note: Oxygen us an element that is also used in the other processes of aerobic respiration like Krebs cycle, glycolysis, pyruvate oxidation as it is aerobic catabolism of carbohydrates to carbon dioxide, water, and energy and this process of aerobic respiration takes place in bacteria and eukaryotes, it is done in the mitochondria.
