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: the energy converters Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria.

Detailed explanation-3: -ATP, or adenosine triphosphate, is chemical energy the cell can use. It is the molecule that provides energy for your cells to perform work, such as moving your muscles as you walk down the street.

Detailed explanation-4: -Aerobic Glycolysis This pathway occurs in the mitochondria of the cell and is used for activities requiring sustained energy production.

Detailed explanation-5: -The energy available from combining molecular oxygen with the reactive electrons carried by NADH and FADH2 is harnessed by an electron-transport chain in the inner mitochondrial membrane called the respiratory chain.
