1. Hypersecretion of cortisol is associated with all of the following except:

A) decreased in protein synthesis

B) Increased blood glucose levels

C) Increased lipolysis

D) Decreased stress resistance

2. When a water-soluble hormone binds to a target cell

A) it enters the cell and travels to the nucleus

B) it triggers up-regulation

C) previously synthesized proteins become active

D) proteins are synthesized on the rough ER

3. Which of the following would you expect to see in someone suffering from secondary hyperthyroidism?

A) low thyroid hormone

B) increased iodine levels

C) low TSH

D) high TSH

Homework Answers

Answer #1

1. ANSWER: Decreases stress resistance.

Reason: Cortisol is a stress hormone which is secreted to increase the resistance towards stress. Its hypersecretion would increase the stress resistance further.

2. ANSWER: it triggers up the regulation.

REASON: Water soluble Hormone binds to the target cells on the plasma membrane amd activates it and it may send feedback to the original hormone producing organ.

3. ANSWER: high TSH.

Reason: Secondary hyperthyroidism is due to the defect seen in the thyroid gland. So there will be high TSH levels to stimulate the thyroid gland to produce hormones.
