Which of the Following Statements About Mitochondrial Division is TRUE

Question

Which of the following statements about mitochondrial division is TRUE?
A)Mitochondria divide in synchrony with the cell.
B)The rate of mitochondrial division is the same in all cell types.
C)Mitochondrial division is mechanistically similar to prokaryotic cell division.
D)Mitochondria cannot divide and produce energy for the cell at the same time.

Accepted Answer

Mitochondrial division is mechanistically similar to prokaryotic cell division because mitochondria are believed to have originated from engulfed prokaryotic cells that evolved into symbiotic organelles. The process of mitochondrial division involves the formation of a constriction ring, similar to the one formed during prokaryotic cell division, that eventually leads to the separation of the two daughter mitochondria. A and B are incorrect statements because mitochondria can divide at different rates in different cell types and do not necessarily divide synchronously with the cell cycle. D is an incorrect statement because mitochondria can produce energy while undergoing division.
