Explanation:

(A) Insulin is a signal protein involved in controlling blood glucose levels.

(B) Carboxylase is an enzyme required in the process of carboxylation.

(C) Rhodopsin is a light sensitive receptor found in the retina of the eye.

(D) Haemoglobin transports oxygen in blood.

(E) Ferritin is a protein that stores iron.

(F) Myosin is a motor protein that carries out its function with actin

(G) Green fluorescent protein has the special purpose of tagging proteins.

(H) Tubulin is a structural protein that gives rise to microtubules that support living cells.

(I) Homeodomain proteins are involved in the regulation of gene expression.
