Question

Which of the following pairs of hormones are not antagonistic (having opposite effects) to each other?

• A. Parathormone - Calcitonin
• B. Insulin - Glucagon
• C. Aldosterone - Atrial Natriuretic Factor
• D. Relaxin - Inhibin

Answer 1

The correct option is D Relaxin - Inhibin

Relaxin - Inhibin is the pair of hormones which are not antagonistic (having opposite effects) to each other.
Relaxin causes pelvic musculature relaxation and inhibin inhibits FSH.

Parathormone increases blood Ca+2 level and calcitonin decreases blood Ca+2 level.

Insulin decreases blood glucose level and glucagon increases blood glucose level.

Aldosterone increases B.P. and ANF decreases B.P.
