Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organelle is responsible for the chemical energy needed for the cell to function?
A
Mitochondria
B
Ribosomes
C
Lysosome
D
Golgi apparatus
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 interact with the endoplasmic reticulum, lysosomes, cytoskeleton, peroxisomes, and nucleus in several ways, ranging from signal transduction, vesicle transport, and membrane contact sites, to regulate energy metabolism, biosynthetic processes, apoptosis, and cell turnover.

Detailed explanation-3: -Most of the energy derived from oxidative metabolism is then produced by the process of oxidative phosphorylation (discussed in detail in the next section), which takes place in the inner mitochondrial membrane.

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: -The most important function of mitochondria is to produce energy through the process of oxidative phosphorylation. It is also involved in the following process: Regulates the metabolic activity of the cell. Promotes the growth of new cells and cell multiplication.
