Question

Quizplus · Accepted Answer

Mitochondria are responsible for extracting energy stored in carbohydrates through a series of metabolic reactions that ultimately produce ATP, water, and carbon dioxide.

Answer: E
 Mitochondria do not synthesize subunits for ribosomes; this is done by the nucleolus in the cell's nucleus. Instead, mitochondria are responsible for the production of ATP.

Answer: J
 Mitochondria do not convert light energy to chemical energy; this is done by chloroplasts in plant cells. Instead, mitochondria are responsible for extracting energy stored in carbohydrates to produce ATP.
