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.
Answer:
Option-A
Explanation:
Vitamin D is an essential nutrient required by the body to maintain its structure as vitamin D helps in the absorption of the calcium and phosphorus which are required in maintaining the bones.
The biosynthesis of vitamin D begins in the skin when the cholesterol, a precursor of the vitamin D gets activated by the Ultraviolet B of the sunlight. When the UV B touch the skin, they convert the precursor to vitamin D3. The vitamin D3 gets transported to the kidney and liver where the enzymatic action converts the vitamin D3 to the active form of vitamin called calcitriol.
Thus, Option-A is the correct answer.
