Which of the following is not required for transport of a mitochondrial protein into the mitochondrion?
A) a matrix localization signal
B) an unfolded protein
C) a proton motive force
D) ATP
E) signal recognition particle

Question

Quizplus · Accepted Answer

The signal recognition particle is not required for the transport of a mitochondrial protein into the mitochondrion. This component is involved in targeting proteins to the endoplasmic reticulum in eukaryotic cells, not mitochondria. Transport into mitochondria relies on a matrix localization signal, an unfolded protein state, a proton motive force, and ATP.
