Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
All cells need energy (ATP) to function. Which cell organelle is responsible for producing energy in the cell? “The Powerhouse”
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. Encyclopædia Britannica, Inc. The “powerhouses” of the cell, mitochondria are oval-shaped organelles found in most eukaryotic cells. As the site of cellular respiration, mitochondria serve to transform molecules such as glucose into an energy molecule known as ATP (adenosine triphosphate).

Detailed explanation-3: -Mitochondria are known as the powerhouse of the cell because it is responsible for the extracting energy from food through cellular respiration. The energy is released in the form of adenosine triphosphate (ATP). It is an energy currency of the cell.

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