cytochrome
n. countable C1 Advanced cy·tochrome
n. a protein in your cells that helps carry energy around. It is very important for keeping your body alive because it helps turn food into energy.
n. a protein complex containing a heme group that functions as an electron carrier in the respiratory chain of cells. It plays a central role in cellular respiration and photosynthesis.
Cytochrome helps your cells produce energy from food.
During cellular respiration, cytochrome acts as a final electron acceptor in the electron transport chain.
The unique absorption spectra of different cytochrome variants allow researchers to track the flow of electrons through the mitochondrial membrane during metabolic stress.
