13. What determines the effect that a hormone will have on a cell?

Negative feedback system regulates secretion of most hormones. The number of hormone receptors can be altered by Up-regulation or Down-regulation. Up-regulation is the increase in the number of available receptors. Down-regulators decrease in the number o

14. What are the major endocrine glands?

The main endocrine glands include the pituitary gland, pancreas, ovaries, testes, thyroid gland, and adrenal glands. The hypothalamus is a neuroendocrine organ.

15. Glycogenolysis is primarily activated by what hormones? .

Glucagon during times of glucose need in the bloodstream. Insulin however, will inhibit the process of Glycogenolysis during times of increased blood sugar levels. Insulin will stop the production of glucagon, which inhibits Glycogenolysis

16. What hormones increase FA mobilization?

As an enzyme, glycogen phosphorylase, acts as a catalase during the rate limiting step of Glycogenolysis. GP will break upWhen the body requires fatty acids as an energy source, the hormoneCortisol - Stimulation of fat breakdown in adipose tissue:The fatt

17. What hormones activate gluconeogenesis?

Cortisol is released during times of low blood sugar in order to release glucose into the blood stream.

18. What hormones help maintain blood glucose levels?

Glucagon and Insulin, Cortisol, Epinephrine, Norepinephrine

19. How do hormones maintain blood glucose levels?

The mobilization of glucose increase is from liver glycogen storage. Glucagon, Epi, NorEpi, Cortisol activate this process,Glucose is made through the process of gluconeogenesis, which is activated by glucagon and cortisol. Entry of glucose into the cell

20.What happens to glucose metabolism if a hormone causes an increase in FA mobilization?

Again GH and cortisol will stop/block the absorption of glucose into the cell during times of FFA mobilization.
