Matt is an athlete, but recently he's been feeling sluggish during practice. he needs to take more breaks because he feels tired. his doctor tells him that an organelle in his cells isn't working as it should. which organelle is most likely the cause of matt's symptoms?

the options are:
golgi apparatus
lysosome
mitochondrion
ribosome
vacuole

The correct answer is "Mitochondrion".

Explanation:

The mitochondrion is a double-membrane-bound organelle that generates most of the cell's supply of adenosine triphosphate (ATP), the most effective and widely used source of chemical energy. The mitochondrion is considered the powerhouse of the cell for producing ATP, therefore, is the most important organelle for producing cells' energy. If Matt is experiencing chronic fatigue, and his doctor tells him that an organelle is not working properly, it is most likely that the doctor is referring to the mitochondrion.
