A) They are the site of adenosine triphosphate (ATP) production.
B) The number of mitochondria in a cell is equal to the number of nuclei.
C) They are replicated within the smooth endoplasmic reticulum (ER).
D) Mitochondrial DNA is inherited patrilineally.
Ans:
A
Feedback:
Consistent with their characterization as the "power plants" of the cell, mitochondria are the site of ATP synthesis for the cell. The number of mitochondria in a given cell type varies, according to the energy demands of the particular cell. They are self-replicating rather than being produced in the smooth ER, and they are inherited matrilineally.
