Justify the statement, “Mitochondria are powerhouses of the cell.”

Answers (1)


Mitochondria are cylindrical structures that are bound in double membranes- an outer membrane and an inner membrane. The outer membrane forms fold like structures called cristae. The cristae are related to the increase in surface area. Mitochondria serves as the main site for aerobic respiration.

They produce cellular energy in the form of Adenosine Triphosphate (ATP). The respiration occurs in two steps- glycolysis and Kreb’s Cycle. Glycolysis occurs in the cytoplasm, whereas Kreb’s cycle occurs in the mitochondria. Energy is not only produced, but it is also stored in the mitochondria for carrying out vital cell functions. Hence, mitochondria are also called the powerhouses of the cell.
