Video Transcript

What feature or requirement of a cell will determine how many mitochondria a cell will contain? (A) The number of proteins the cell needs to synthesize. (B) The number of times the cell needs to differentiate. (C) The number of nutrients the cell requires. (D) The amount of energy the cell requires.

Some cells, like epithelial cells, contain very few mitochondria. While others, like muscle cells, contain many. Why is this? You’ll recall that mitochondria are organelles specific to eukaryotes. And their primary function is the release of energy through cellular respiration. Because muscle cells have a higher requirement for energy than epithelial cells, they contain more mitochondria.

Therefore, the option that correctly describes what determines the number of mitochondria in a cell is given by answer choice (D): the amount of energy the cell requires.
