Question

B] the release of glucagon in response to low blood sugar.
C] increased cell expansion and growth.
D] ALL OF THESE
3.Which of the following is NOT a hormone involved in the Resistance Reaction?
A] Cortisol
B] Aldosterone
C] HGH
D] Insulin
4. A large amount of hormone is required to produce an effect. TRUE OR FALSE
5. Hormones that target neural cells are called tropic hormones. TRUE OR FALSE
6. The sensitivity of a target cell to one type of hormone depends on the number of receptors available in that cell type. TRUE OR FALSE.
7. During upregulation of a hormone response.
A] the number of receptors decreases.
B]the number of receptors increases.
C] the amount of hormone increases.
D] none of these.
8. A example of a positive feedback loop would be:
A] the release of a hormone in response to a single stimulus.
B] the release of glucagon in response to low blood sugar.
C]the release of oxytocin in response to stretching of the uterus.
D] All of these
Explanation / Answer
(Since you have posted several questions together, I am answering the first four)
1. True. Although proteins produced by a hormone-receptor binding will mostly alter the activity of other cells, they can also alter the cell's own activity.
2. A. Growth hormone causes lipolysis during the resistance response. Anabolic effects such as cell expansion, and growth are not seen.
3. D. Insulin is not a part of resistance response. Cortisol and HGH provide energy and aldosterone restores blood volume.
4. False. Hormones act in very minute quantities.
