Detailed explanation-1: -Mitochondria play a critical role in the generation of metabolic energy in eukaryotic cells. As reviewed in Chapter 2, they are responsible for most of the useful energy derived from the breakdown of carbohydrates and fatty acids, which is converted to ATP by the process of oxidative phosphorylation.

Detailed explanation-2: -Mitochondria Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions.

Detailed explanation-3: -Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration.

Detailed explanation-4: -At the inner mitochondrial membrane, a high energy electron is passed along an electron transport chain. The energy released pumps hydrogen out of the matrix space. The gradient created by this drives hydrogen back through the membrane, through ATP synthase.
