the mitochondria are often called the “powerhouse of the cell” because:
they regulate gene expression
they produce atp through cellular respiration
they synthesize proteins
they store energy as atp

Explanation:

Mitochondria are known as the "powerhouse of the cell" because they generate ATP, the energy - currency of the cell, through cellular respiration. Gene expression is regulated by various nuclear and cytoplasmic factors, not mainly by mitochondria. Protein synthesis occurs in ribosomes. Mitochondria produce rather than just store ATP.

Answer:

They produce ATP through cellular respiration
