Answer:
The process that takes place in the mitochondrion is ATP production.
Explanation:
Mitochondria are organelles that specialize in the production of ATP, giving the cell all the energy it needs for every energy-consuming process. In order to produce this energy the mitochondrion uses a glucose molecule and, by many complex chemical reactions, it reduces it to simpler molecules that will be used in its last step: the oxidative phosphorylation.
Photosynthesis is only made by chloroplasts (in plants) and some bacteria.
Anaerobic respiration also produces energy from glucose but only happens when there's no contact with oxygen and doesn't happen on the mitochondria.
Synthesis of glucose occurs in the endoplasmic reticulum.
