A) Calcitonin and thymosin - Thyroid hormones
B) Pepsin and prolactin - Two digestive enzymes secreted in stomach
C) Troponin and myosin - Complex proteins in striated muscles
D) Secretin and rhodopsin ? Polypeptide hormones
Correct Answer: C
Solution :
[c] Troponin is a protein which is found on actin filament and myosin protein is found in myosin filament. Both actin and myosin are complex proteins in striated muscles. Thymosin is a hormone secreted by the thymus that stimulates development of T- cells. Prolactin is a hormone released by the pituitary gland that stimulates breast development and milk production in women. Rhodopsin, also known as visual purple, is not a hormone. It is a biological pigment in photoreceptor cells of the retina that is responsible for the first events in the perception of light.
