GENERAL HISTOLOGY

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 powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell.

Detailed explanation-3: -Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria.

Detailed explanation-4: -The sugar in the food we eat has lots of energy stored inside. Our cells break the sugar down into a chemical called pyruvate, which our mitochondria take and turn into other molecules in a few stages of chemical reactions. As they do so, energy is extracted and transferred into ATP.

Detailed explanation-5: -Cellular respiration is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions. Cellular respiration takes place in the cells of animals, plants, and fungi, and also in algae and other protists.
