|
It is the site where oxygen combines with small molecules and releases large amounts of energy.
|
|
|
It is the site where food is broken down into small molecules and amounts of energy.

Detailed explanation-1: -Answer: 3. It is the site where oxygen combines with small molecules and releases large amounts of energy.
Detailed explanation-2: -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-3: -Known as the “powerhouses of the cell, ” mitochondria produce the energy necessary for the cell’s survival and functioning.
Detailed explanation-4: -Mitochondria have an important role in cellular respiration through the production of ATP, using chemical energy found in glucose and other nutrients. Mitochondria are also responsible for generating clusters of iron and sulfur, which are important cofactors of many enzymes.
Detailed explanation-5: -Production of ATP. Perhaps the most well-known role of mitochondria is the production of ATP, the energy currency of cells. Calcium Homeostasis. Regulation of Innate Immunity. Programmed Cell Death. Stem Cell Regulation. 06-Jun-2017
