Detailed explanation-3: -Glycogen is a complex carbohydrate that is made by animals and fungi to store energy.

Detailed explanation-4: -Mitochondria is responsible for the production of energy in the cell. Mitochondria is also known as the powerhouse of the cell. It has a double membrane-bound structure. They are found inside the cytoplasm of the cell and synthesize energy in the form of ATP molecules.

Detailed explanation-5: -Adenosine 5’-triphosphate, or ATP, is the most abundant energy carrier molecule in cells. This molecule is made of a nitrogen base (adenine), a ribose sugar, and three phosphate groups.
