Explanation

The primary function of haemoglobin (Hb) is to transport oxygen in blood. Myoglobin contains a heme (prosthetic) group, which is responsible for its main function (carrying of oxygen molecules to muscle tissues). Cytochrome c is a component of the electron transport chain in mitochondria. Catalase in an enzyme produced by our liver to break down hydrogen peroxide.
