Answer: Chemical Energy
Step-by-step explanation:
Cellular respiration involves the breaking down of glucose to release energy.
Energy in glucose is release slowly and used to form molecules of adenosine triphosphate which is the energy used by cells to carry out biochemical process.
C6H12O6+6O2⟶6CO2+6H2O+Energy
Energy that is released during the process is chemical energy in adenosine triphosphate, this energy is then made available to the cell.
