Answer:
The main role of mitochondrion is the production of ATP (adenosine triphosphate).
Step-by-step explanation:
The main role of mitochondrion is the production of ATP (adenosine triphosphate). ATP is obtained, for example, through the phosphorylation of ADP [adenosine diphosphate]).
Mitochondrion obtain energy through aerobic respiration. When oxygen is scarce, they can obtain it by anaerobic fermentation, though.
Mitochondrion have many other functions and roles.
