Why does endocrine signaling result in a long-term response? Question 24 options: A. The hormone is bound covalently to the receptor B. The hormone is metabolized slowly C. The receptor has a high affinity for hormone D. There is a high concentration of hormone in blood E. There is a rapid rate of synthesis of hormone

Expert Solution

The endocrine signalling is the signalling where the endocrine hormone gets secreted in one part of the body and travells into the to internal organs of the body where it gives effect which takes longer for enzyme to travel and provide its effect hence the effect of endocrine enzymes is slow but longer acting.

The longer travel of the hormon in blood makes the concentration of hormone in blood low so option D is not right.

Option E is not right as synthesis of hormon has no significant effect on its long action.

Option C is not right as the high affinity of receptor is not always related to long action.

Endocrine hormones bing to the receptor by lock and key model so it remains bounded to receptor for longer time to provide long term effect. So option A is right.

Moreover the hormone travels longer in blood stream to other parts of body hence its metabolism is slow so option B is also right.

Answer A & B.
