Question

The hormones with antagonistic action are

• A. Adrenaline and Nonadrenaline
• B. Glucocorticoid and Mineralocorticoid
• C. Insulin and Glucagon
• D. Thymosin and Parathormone

Answer 1

The correct option is C Insulin and Glucagon

Insulin serves to lower the blood glucose level by stimulating the uptake of glucose by cells, specifically muscle cells, liver cells and adipose tissues cells. Glucagon hormone from pancreas stimulates liver to break down glycogen into glucose and use of fat and protein as glucose source thereby increasing the blood glucose level. Both hormones regulate the blood sugar level by their antagonistic effects.

Adrenaline and noradrenaline are the secreted by adrenal medulla under emergency condition to prepare the body for flight or fight response by increasing the intensity of effect of sympathetic stimulation and response.

Mineralocorticoids accelerate the renal reabsorption of sodium and excretion of potassium thereby increasing the blood sodium and decreasing the body potassium concentration. Glucocorticoids/ cortisol prepare the body for long term stress response by stimulating anti stress mechanisms which includes stimulation of protein and fat metabolism, reduced inflammation etc.

Parathyroid hormone of parathyroid gland reduces the blood phosphate level while increases the blood calcium level while thymosin serves as anti-implant factor.

Therefore, the correct answer is option C.
