ANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -Cellular respiration is the process by which the energy in food is converted into energy that can be used by the body’s cells. The energy stored in glucose is transferred to ATP. The process can be summarized as: glucose + oxygen carbon dioxide + water.

Detailed explanation-3: -To meet this energy demand, muscle cells contain mitochondria. These organelles, commonly referred to as the cell’s “power plants, ” convert nutrients into the molecule ATP, which stores energy.

Detailed explanation-4: -Animal cells get energy from food, while plant cells get energy from sunlight. All cells use chemical energy. is the energy stored in the bonds between atoms of every molecule. To stay alive, cells must be able to release the chemical energy in the bonds.

Detailed explanation-5: -The classic role of mitochondria is oxidative phosphorylation, which generates ATP by utilizing the energy released during the oxidation of the food we eat. ATP is used in turn as the primary energy source for most biochemical and physiological processes, such as growth, movement and homeostasis.
