Question 1

secrete hormones into the blood

Answer 1

endocrine glands

Question 2

precursors for prohormobes

Answer 2

prehormones

Question 3

precursors of hormones

Answer 3

prohormones

Question 4

What is the purpose of a pro hormone?

Answer 4

for the enhancement and strengthening of a hormone that already exists in the body

Question 5

are derived from tyrosine and tryptophan

Answer 5

amines (thyroid hormone and catecholamines)

Question 6

chains of amino acids

Answer 6

polypeptides and proteins

Question 7

proteins bound to carb groups include LH FSH and TSH

Answer 7

glycoproteins

Question 8

derived from cholesterol (sex hormones and adrenal gland hormones)

Answer 8

steroids

Question 9

small chemical messengers that travel through our bloodstream to target cells

Answer 9

hormones

Question 10

when two or more hormones work together to produce a particular result

Answer 10

synergistic

Question 11

When the action of one hormone enhances the responsiveness of the target organ to a second hormone.

Answer 11

permissive effect

Question 12

When the action of one hormone is inhibited by another hormone

Answer 12

antagonistic effect

Question 13

chronically low levels of hormone in ECF leads to increase of number and sensitivity of protein receptors for that hormone —– upregulation

Answer 13

priming effect

Question 14

– chronically high levels of hormone in the ECF leads to decrease in the number and sensitivity of protein receptors for that hormone
– Prevented by pulsatile secretions

Answer 14

Downregulation/Desensitization
