ferricytochromes

Example:In the electron transport chain, ferricytochrome c plays a crucial role in transferring electrons to oxygen during cellular respiration.

Definition:A specific ferricytochrome that has iron in the ferric (oxidized) state and can accept electrons in biochemical redox reactions, commonly found in the electron transport chain of cells.

Example:Ferricytochrome oxidase is essential in the last step of aerobic respiration, where electrons from ferricytochromes are transferred to oxygen to produce water.

Definition:An enzyme that catalyzes the reduction of molecular oxygen to water, involving the electron transfer from ferricytochrome groups.
