Detailed explanation-1: -Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP).

Detailed explanation-2: -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: -During this stage, each pyruvate molecule in the cytoplasm enters the mitochondrion, where it is converted into acetyl CoA, a two-carbon energy carrier, and its third carbon combines with oxygen and is released as carbon dioxide.

Detailed explanation-4: -Mitochondria burn oxygen and provide energy for the body. Cells lacking oxygen or nutrients have to change their energy supply quickly in order to keep growing.

Detailed explanation-5: -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).
