Molecular model of complex III consisting of the mitochondrial cytochrome bc1 complex subunit 1 (UQCRC1) and the subunit 2 (UQCRC2). Complex III plays a crucial role in the electron transport chain by transferring electrons from ubiquinol (QH2) to cytochrome c. This process helps create a proton gradient across the inner mitochondrial membrane, which is then used by ATP synthase to generate ATP (cellular energy).
