Detailed explanation-1: -Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Detailed explanation-2: -Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.

Detailed explanation-3: -Chloroplasts and mitochondria are the major ATP producing organelles in plant leaves.

Detailed explanation-4: -Mitochondria are the organelle where ATP is generated through oxidative phosphorylation and several diseases are associated with mitochondrial dysfunction and oxidative stress.

Detailed explanation-5: -Mitochondria are known as the powerhouse of cells. It is because the mitochondrion is the site of cellular respiration where energy in the form of ATP (Adenosine triphosphate) is generated as a result of oxidation of food constituents. This energy is required for various chemical activities needed for life.
