This is the “powerhouse” of the cell that converts food to energy.
A
Mitocondria
B
Endoplasmic Reticulum
C
Nucleus
D
Lysosome
Explanation: 

Detailed explanation-1: -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-2: -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).

Detailed explanation-3: -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-4: -The process that converts food energy into ATP is cellular respiration. Cellular respiration starts in the mitochondria of cells. It consists of sugar molecules being broken apart and used to produce ATP with oxygen present. Water and carbon dioxide are also products.

Detailed explanation-5: -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.
