2. 1QQ#6 10:30
Write A B C D E and circle the letter of each correct response.
In the paper by King et al., A) Rice flour suppressed the secretion of FSH and LH. B) Supplemental andro is converted to estrogens. C) Resistance training in combination with Andro supplementation produced larger gains in muscle strength than resistance training alone. D) The manuscript was accepted for publication in several journals but the authors elected to have it published in JAMA. E) Grant proposals and research papers must include a description of the procedures and statements of purpose.

3. 1QQ#7 10:30
Write A B C D E and circle the letter of each correct response.
A) The catecholamine hormones are dissolved in the plasma. B) Steroid hormones are derivatives of tyrosine. C) Any newly discovered hormones will probably be amine hormones. D) The receptors for peptide hormones are typically located inside the target cell. E) Thyroid hormones and steroid hormones are transported as bound and free forms in the plasma.

4. 1QQ#6 11:30
Write A B C D E and circle the letter of each correct response.
In the paper by King et al., A) Andro supplementation suppressed the secretion of FSH and LH. B) The authors emphasize the hazardous effects of Andro supplementation on liver function and cholesterol metabolism. C) Resistance training in combination with Andro supplementation produced the same gains in muscle strength as resistance training alone. D) The manuscript was accepted for publication in several journals but the authors elected to have it published in JAMA. E) Grant proposals and research papers must include a description of the procedures and statements of purpose.

5. 1QQ#7 11:30
Write A B C D E and circle the letter of each correct response.
A) The catecholamine hormones are bound to proteins in the plasma. B) Peptide hormones are derivatives of tyrosine. C) Any newly discovered hormones will probably be peptide hromones. D) The receptors for peptide hormones are typically located inside the target cell. E) Thyroid hormones and steroid hormones are transported as bound and free forms in the plasma.

6. Steroid hormones

not soluble in plasma, not storable in vesicles
Bound & Free

Target cells have intracellular receptors, some on cell membrane. Change gene expression. Timecourse: longer latency, longer lasting.

9. Explain why a given cell produces one category of steroid hormones and no others.
= Aromatase

10. What happens to hormones once released?
Be able to give
Examples.
Ex: Renin
Fast if free
Slow if bound
T4 to T3 and Testosterone to Estradiol

12. Factors that affect hormone secretion
Na+, K+, Ca++, Glucose, etc.
NE, ACh, etc.
Incretins, EPI, DA, etc.
Integrator!

Recall example: beta cells of Islets of Langerhans
Secretion is usually pulsative, may be diurnal.

15. Tropic hormones control the function
Trophic hormones promote survival and growth of targets
