Options

A. lysine, glycine, thiamine - amino acids
B. myosi, oxytocin and gastrin- harmones
C. rennin, helicase and hyaluronidase -enzymes
D. optic nerve, oculomotor, vagus - sensory nerves

Answer

c

Explanation

Remmin, helicase and hyaluronidase are all enzymes. Renin (chymosin) secreted by the stomach is responsible for clotting milk. It acts on a soluble milk. It acts milk protein (vaseinogen)to converts it into the isoluvble form casein. Helicase unwinds double stranded helical DNA during replication. Hyalurondiase is able to digest hyaluronic acid (major glycosaminoglycan) & is therefore important in modulating the removal of cell matrix in order to facilitate cell movemnt of tissue organization. Thiamine is not an amio acid it is vitamin `B_(1)`, which is active in the form of thiamin pyrophosphate, coenzyme in decarboxylation reaction in carbpohudrate metabolism. A deficiency of vitamin `B_(1)` leads to beri beri.
Muyosin is a contractile protein that interacts with acting to bring about contraction of muscle or cell movement.
Among optic, oculamotor and vagus, which are cranial nerves, optic is sensor in nature, oculomotor is motor and vagus is mixed sensory nerves.
