The cells involved in active transport require energy to move molecules or ions against their concentration gradient, from a region of low concentration to a region of high concentration. Mitochondria, being the powerhouses of the cells, produce energy in the form of ATP through cellular respiration, which is essential for active transport.
Therefore, to carry out the energy-demanding process of active transport, cells require a significant amount of ATP, and having many mitochondria will ensure that there is a constant supply of ATP available. This is the reason why cells involved in active transport, such as muscle cells and nerve cells, contain a large number of mitochondria to support the energy needs of the cell...
