Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What organelle is responsible for ATP energy production?
A
nucleus
B
mitochondria
C
ribosome
D
cell membrane
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: -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-3: -The mitochondrion is referred to as the ‘power house’ of the cell, because it is responsible for the synthesis of the majority of ATP under aerobic conditions. The inner membrane of the mitochondrion contains the components of the electron transport chain.

Detailed explanation-4: -ATP synthesis takes place in the ATP synthase complex of the Electron transport chain, which is found in the inner mitochondrial membrane.
