PATHOLOGY

Detailed explanation-1: -The process of ATP synthesis and cellular respiration takes place inside the mitochondria. Hence, mitochondria are the cell organelle that releases the most energy.

Detailed explanation-2: -Mitochondria 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).
