Question

Quizplus · Accepted Answer

Quinone (also known as ubiquinone or coenzyme Q) serves as an electron carrier in the mitochondrial electron transport system, shuttling electrons from complex I and II to complex III. Protons and water are involved in the generation of ATP through oxidative phosphorylation, but not in the electron transport system. ATP itself is not an electron carrier, but rather a molecule that stores energy for cellular use.
