Mitochondria is called the powerhouse of cell. They are so called because they carry out the process of aerobic respiration and generate the energy molecules (ATP or adenosine Triphosphate) for cell operation.Click to see full answer. Thereof, what is the powerhouse of the cell? Mitochondria – Turning on the Powerhouse 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. The biochemical processes of the cell are known as cellular respiration.Likewise, why are mitochondria called the powerhouse of the cell worksheet answers? Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell. Mitochondria is the powerhouse of the cell because it produces energy to the cell. Furthermore, why mitochondria is called as powerhouse of the cell? Mitochondria (sing. Mitochondrion) are known as the powerhouse of the cell because they are responsible for the release of energy from food ,i.e, cellular respiration. This energy is released in the form of ATP (adenosine triphosphate), the energy currency of the cell.Is mitochondria really the powerhouse of the cell?Mitochondria have been described as “the powerhouses of the cell” because they generate most of a cell’s supply of chemical energy. All eukaryotic cells contain a nucleus and little organelles — and one of the most famous was the mitochondrion.
