During the gap between DNA synthesis and mitosis, the cell will continue to grow and produce new proteins. At the end of this gap is another control checkpoint (G2 Checkpoint) to determine if the cell can now proceed to enter M (mitosis) and divide.
Energy changes forms from heat, to kenetic, to potential energy. However, the total energy is the atmosphere is conserved, meaning energy can only change forms, but cannot be produced.
