Which of the following pairs of hormones are not antagonistic (having opposite effects) to each other?
Parathormone - Calcitonin
Insulin - Glucagon
Aldosterone - Atrial Natriuretic Factor
Relaxin - Inhibin
The non-antagonistic pair of hormones is:
Option 4) Relaxin - Inhibin
Relaxin and inhibin are both peptide hormones, but they have different functions and are not antagonistic to each other. Relaxin is primarily involved in the relaxation of smooth muscles and the regulation of reproductive processes, while inhibin is involved in the inhibition of follicle-stimulating hormone (FSH) secretion.
Option 1) Parathormone - Calcitonin: Parathormone and calcitonin are antagonistic hormones involved in the regulation of calcium and phosphate levels in the body.
Option 2) Insulin - Glucagon: Insulin and glucagon are antagonistic hormones involved in the regulation of blood sugar levels. Insulin decreases blood sugar levels, while glucagon increases blood sugar levels.
Option 3) Aldosterone - Atrial Natriuretic Factor: Aldosterone and atrial natriuretic factor (ANF) are antagonistic hormones involved in the regulation of blood pressure and sodium balance in the body.
