Answer:
Muscles cells
Step-by-step explanation:
Energy is required by all the cells but muscle cells more energy. As muscle cells help in body movement so they continuously contract and expand which requires a large amount of energy and this energy is provided by ATP.
Mitochondria are responsible for making ATP in the cells and the evidence that muscle cells require most ATP is the presence of more mitochondria in muscle cells than other body cells which helps muscle cells to provide more amount of ATP or energy.
Liver cells also contain a large number of mitochondria because they need energy for regeneration.
