Vedclass · Answer

(D) In the Electron Transport System $(	ext{ETS})$,ubiquinone (also known as Coenzyme $Q$) acts as a mobile electron carrier within the inner mitochondrial membrane.It receives reducing equivalents (electrons) from two main sources:$1$. From $	ext{Complex } I$ ($	ext{NADH}$ dehydrogenase) via the oxidation of $	ext{NADH}$.$2$. From $	ext{Complex } II$ (Succinate dehydrogenase) via the oxidation of succinate to fumarate.Since $	ext{Complex } II$ is one of the primary donors of electrons to ubiquinone,the correct option is $	ext{Complex } II$.

During $\text{ETS}$,ubiquinone receives reducing equivalents via
