Question

what is the principal function of mitochondria?
atp production
lipid synthesis
motility
dna synthesis
secretion

Explanation:

Mitochondria are known as the power - houses of the cell. Through cellular respiration, they generate adenosine triphosphate (ATP), the energy - currency of the cell. Lipid synthesis mainly occurs in the endoplasmic reticulum, motility is related to structures like cilia and flagella, DNA synthesis occurs in the nucleus (for most of the cell's DNA), and secretion is related to Golgi apparatus and vesicles.

Answer:

ATP production
