NEET BIOLOGY

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 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).

Detailed explanation-3: -Mitochondria are known as the powerhouse of cells. It is because the mitochondrion is the site of cellular respiration where energy in the form of ATP (Adenosine triphosphate) is generated as a result of oxidation of food constituents. This energy is required for various chemical activities needed for life.

Detailed explanation-4: -Mitochondria are semi-autonomous organelles that are descendants of endosymbiotic bacteria. Mitochondria play a pivotal role in cellular energy production through the mitochondria-housed pathways of citric acid cycle, fatty acid oxidation, respiration and oxidative phosphorylation (OXPHOS).
