Which of the following is a lipid-soluble component involved in the electron transport chain during cellular respiration?

Explanation

Ubiquinone, also known as Coenzyme Q, is a lipid-soluble molecule that plays a crucial role in transferring electrons within the electron transport chain. Flavoproteins, cytochromes c1 and a, and iron-sulfur proteins are protein components, whereas ubiquinone is a non-protein, mobile electron carrier.
