Energy coupling is the transfer of energy from the energy forming step to the biomolecule forming step. The energy forming step is called catabolism wherein the complex molecules are broken down and releasing energy. The energy produced is then used the process called anabolism which produces biomolecules such as proteins.
Mitosis is an asexual method of reproduction, and so is binary fission.
