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. They generate adenosine triphosphate (ATP), which is the energy currency of the cell. When Brenda is using her legs to paddle the boat, her muscle cells need energy. Mitochondria in these muscle cells will produce ATP through cellular respiration (a process that breaks down glucose in the presence of oxygen). Centrioles are involved in cell division (formation of spindle fibers). Lysosomes are for digestion of waste materials in the cell. Ribosomes are for protein synthesis. Vacuoles (in plant cells, they store water and other substances; in animal cells, they are less prominent and have functions like storage of some materials) do not play a role in energy production for this activity.

Answer:

C. mitochondria
