All life processes such as growth, reproduction require a constant supply of nutrients and most importantly energy be introduced into the body. For every biological or cellular process individual needs energy. The cell cycle or growth cycle requires the coordinated production of energy for many processes. Energy also required for the synthesis of the system essential for DNA replication and mitosis.
Energy and the growth cycle relation is bidirectional, and various cell-cycle checkpoints lead to the cell-cycle arrest or exit due to energy deficits in the cell.
All the cells in a person's body have the same DNA and the same genes. However, the difference between cells in different tissues and organs is that the "expression" of the genes differs between cells. Expression means that the message from the DNA is being copied and made into protein.
