NEET BIOLOGY

Detailed explanation-1: -Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. Apart from cellular respiration, mitochondria also play a key role in the ageing process as well as in the onset of degenerative disease.

Detailed explanation-2: -Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. In cellular respiration sugar with the help of oxygen is broken down into ATP (energy molecule).

Detailed explanation-3: -In order to create more ATP, our mitochondria go through a series of chemical reactions to break down our food, particularly glucose, amino acids, and fatty acids.

Detailed explanation-4: -Our mitochondria take our glucose molecules through a process called cellular respiration which is essentially just a process of breaking down and converting glucose by combining oxygen with a glucose molecule.
