Question

Mary is about to face an interview. But during the first five minutes before the interview she experiences sweating, increased rate of heart beat, respiration, etc. Which hormone is responsible for her restlessness?

• A. Estrogen and progesterone
• B. Oxytocin and vasopressin
• C. Adrenaline and noradrenaline
• D. Insulin and glucagon

Answer 1

The correct option is C Adrenaline and noradrenaline

Mary, during her first five minutes before interview experiences sweating, increased heart rate and respiration because she is having stress which leads to release of emergency hormones or hormones of flight and fight, i.e., adrenaline and noradrenaline. These hormones stimulate the breakdown of glycogen resulting in increased concentration of glucose in blood.

Estrogen and progesterone: These are secreted from the ovary and play a major role in development of secondary sexual characters, oogenesis and pregnancy.

Oxytocin and vasopressin: Oxytocin is involved in contraction of smooth muscles of uterus at the time of child birth in females and acts mainly on mammary gland for milk ejection. Vasopressin stimulates the absorption of water and electrolytes by distal tubules in kidney and also reduces loss of water.

Insulin and glucagon are the peptide hormones. Insulin decreases blood glucose level and glucagon increases the blood glucose level.
