Question

Quizplus · Accepted Answer

Mitochondria are responsible for energy production in cells through the process of cellular respiration. Cells that have a high energy demand, such as muscle cells or cells involved in active transport, require a large number of mitochondria to meet their energy needs. Therefore, the presence of large numbers of mitochondria in a cell suggests a high energy demand.
