Answer:

The primary role of oxygen in cellular respiration is to make energy.

Explanation:

When we breathe our lungs inhale and exhale air. This is the way our body has to get in what we need the most: Oxygen. This is the star of the cellular respiration.

Cellular respiration is a process where the cells are able to make energy. Oxygen is needed in this process for organisms who have an aerobic respiration. Other organisms like some bacterias have an anaerobic respiration which does not need oxygen. In those cases, they have other mechanisms of making energy.  

So we must talk about Aerobic Respiration, which uses Oxygen. Every cell in our body is engaged in this process. Cells use this element and glucose. Glucose is a type of sugar found in foods like fruits, cereals, sweets and many more. It has a lot of different steps. It starts converting glucose into ATP (adenosine triphosphate), or cellular energy, and carbon dioxide.

Oxygen plays an important role in cellular respiration as it serves as the final acceptor for electrons from the electron transport chain.

Cellular respiration refers to the process that cells used to make energy.  Our body cells require oxygen to perform cellular respiration. Generally, the body cells take part in cellular respiration.

Further Explanation

In this process, our body cells make oxygen and glucose and convert them to carbon dioxide and cellular energy

Some of the steps involved in cellular respiration include

  • Glycolysis
  • Citric Acid Cycle
  • Oxidative phosphorylation

Glycolysis: this is the first step involved in cellular respiration. This step takes place in the main section of the cell called cytoplasm. The individual body cells allow glucose to enter from the blood, the glucose present in the blood is from the food we consume.

The cells now convert the glucose into many compounds to form ATP molecules and other molecules known as pyruvate including a compound called NADH. The electrons derived from the glucose are also stored by the molecule.

Citric Acid Cycle: at this step, the body cells take the molecules,  pyruvate and also convert to another molecule known as acetyl Co-A. The acetyl Co-A is also regenerated as part of the citric cycle. This cycle also created additional NADH, a molecule of ATP and molecule FADH.

Oxidative phosphorylation: at this point, all the molecules have been created and now focuses on the electrons that are present in NADH. The NADH is however taken to the mitochondria membrane.
