Fe+2 is a cofactor of:
Correct answer: A. Chrome oxidase
- A. Chrome oxidase
- B. Carbonic anhydrase
- C. Glucose 6-phosphatase
- D. Both a and b
Explanation
Chrome oxidase is indeed an enzyme that utilizes iron as a cofactor. It's involved in the electron transport chain, specifically in the reduction of oxygen to water. The iron atom in the heme group of chrome oxidase plays a crucial role in this process.Why it's correct: Chrome oxidase relies on the iron atom in its heme group to facilitate electron transfer during the reduction of oxygen.

About Macromolecules
Proteins are classified by shape, composition and structure, from primary amino acid sequence to secondary, tertiary and quaternary organisation, and their biological roles are linked to this structure. Enzymes are examined as protein biocatalysts, including active sites, substrate specificity, activation energy, cofactors and factors affecting activity.
