What does the mitochondrion produce that causes it to often be called the powerhouse of the cell?
Correct Answer: A
Rationale: The mitochondrion produces ATP (adenosine triphosphate), which is the primary energy currency of the cell. This energy production is why mitochondria are referred to as the powerhouse of the cell. ATP generated by mitochondria is essential for various cellular processes, such as muscle contraction, cell division, and macromolecule synthesis, making it a crucial organelle for cell function.
