What primary function do mitochondria serve in a human cell?

Mitochondria,the powerhouse of the cell.

Reached waaaay back to sophomore biology for that one! 😁

Thanks to Madeleine L’Engle I knew this. In the sequel to A Wrinkle in Time, Charles Wallace’s lethargy is due to a problem with his mitochondria. Great kid’s book!

Wow did not know they had their own DNA, well your mother's mtDNA. Love this quiz!
