Question

mitochondria are known as the powerhouse of the cell. Why?

Answer 1

Explanation:

Mitochondria are organelles that are responsible for making adenosine triphosphate (ATP), the cell’s main energy-carrying molecule.

Mitochondria contain their own ribosomes and DNA; combined with their double membrane, these features suggest that they might have once been free-living prokaryotes that were engulfed by a larger cell.

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.

Answer 2

Because they provide energy for all the activities .This energy is produced by the oxidation of food .Thus,they are often called powerhouse of the cell.
