All cells need energy to function. Which cell organelle is responsible for producing energy in the cell?
A
chloroplasts
B
mitochondria
C
nucleus
D
vacuoles
Explanation: 

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: -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-4: -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.

Detailed explanation-5: -Mitochondria are responsible for converting nutrients into the energy-yielding ATP to power the cell’s activities.
