Vedclass · Answer

(A) In the Electron Transport System $(ETS)$ of mitochondria,electrons are transferred through a series of complexes. $Ubiquinone$ ($UQ$ or $Coenzyme-Q$) is a lipid-soluble,small molecule that is not permanently attached to any protein complex. It acts as a mobile electron carrier that shuttles electrons between $Complex-I$ ($NADH$ dehydrogenase) and $Complex-III$ ($Cytochrome-bc_1$ complex),as well as from $Complex-II$ ($Succinate$ dehydrogenase) to $Complex-III$. Therefore,$UQ$ is the correct answer.

Which of the following components of $ETS$ acts as a mobile electron carrier?
