Question

select the correct answer.
brenda and her friend are relaxing in a paddleboat, slowly working the paddles with their legs to move the boat. which organelles in the muscle cells of brendas legs enable brenda to have the energy for this activity?
a. centrioles
b. lysosomes
c. mitochondria
d. ribosomes
e. vacuole

Explanation:

Mitochondria are known as the "powerhouses" of the cell, as they produce ATP (adenosine triphosphate), the primary energy currency used by cells for activities like muscle contraction. Centrioles assist in cell division, lysosomes break down waste, ribosomes make proteins, and vacuoles store materials—none of these directly supply energy for muscle movement.

Answer:

C. mitochondria
