WebJul 30, 2024 · Ubiquinones and Cytochromes are two efficient and important electron carriers in the process of respiration. Ubiquinones are lipid soluble, hydrophobic small organic molecules. On the other hand, cytochromes are heme-containing protein molecules. This is the key difference between Ubiquinones and Cytochromes. WebThere are two heme groups where each of them is present in cytochromes c and a3. The cytochromes are responsible for holding oxygen molecule between copper and iron until the oxygen content is reduced completely. In this phase, the reduced oxygen picks two hydrogen ions from the surrounding environment to make water.
