Multiple Choice
In a typical eukaryotic cell, where are mitochondria primarily located?
A
Within the lumen of the rough endoplasmic reticulum
B
Embedded within the plasma membrane as transmembrane ATP-producing complexes
C
Inside the nucleus, adjacent to chromatin
D
Free in the cytosol, often positioned near areas of high ATP demand
Verified step by step guidance1
Recall the primary function of mitochondria, which is to produce ATP through cellular respiration, supplying energy to the cell.
Understand the cellular architecture: mitochondria are organelles that are not enclosed within other organelles like the rough endoplasmic reticulum or the nucleus.
Recognize that mitochondria are dynamic and often move within the cytosol to localize near regions where energy demand is high, such as near muscle fibers or synapses.
Eliminate incorrect options by considering their biological plausibility: mitochondria are not embedded in the plasma membrane nor located inside the nucleus.
Conclude that mitochondria are primarily found free in the cytosol, strategically positioned near areas of high ATP demand to efficiently supply energy.
