Cellular respiration

Explanation:

Respiration is the process by which energy is made. Aerobic respiration requires oxygen.

All the other processes listed do not require oxygen to.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
