GENERAL HISTOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Mitochondria are well known as the powerhouse of the cell, and as discussed in the section on Generation of ATP: Bioenergetics and Metabolism, in an active tissue such as heart, they are responsible for generating most of the ATP in the cell.

Detailed explanation-3: -Most of the energy derived from oxidative metabolism is then produced by the process of oxidative phosphorylation (discussed in detail in the next section), which takes place in the inner mitochondrial membrane.

Detailed explanation-4: -Mitochondria is a cell organelle which is also called the powerhouse of the cell. Some processes of cellular respiration take place here, like the Kreb cycle and oxidative phosphorylation. By the reduction of many compounds, energy is produced in the form of NADH2 and FADH.

Detailed explanation-5: -Mitochondria are the powerhouses of the cell because they “burn” or break the chemical bonds of glucose to release energy to do work in a cell. Remember that this energy originally came from the sun and was stored in chemical bonds by plants during photosynthesis.
