Set A

1.      Major difference of a hormone from an enzyme.

A hormone is an initiator of biochemical reactions, while an enzyme is a catalyst.

2.      The hormone tested in pregnancy test

Human Chorionic Gonadotropic Hormone (HCG)

3.      Hormone responsible for contraction of uterus during the birthing process.

oxytocin

4.      Also called somatostatin

Growth Hormone Inhibitory Hormone (GHIH or GHIF)

5.      Also called the master gland

9.      Anterior pituitary hormones

FSH, ACTH, FSH, LH, PrL, GH

Set B

1.       3 Hormones produced by thyroid gland

T3, T4, calcitonin

2.      Major carrier protein of thyroid hormones

TBG

3.      Where is acridinium ester used in TFT?

Automated method

4.      3 carrier proteins for thyroid hormones

Albumin, TBPA, TBG

5.      Pathway for T3, T4 secretion.

T3, T4 concentration acts as the stimulus for increased or decreased TRH secretion. TRH acts on anterior pituitary to increase or decrease secretion of TSH. TSH stimulates the thyroid gland to increase or decrease secretion of T3 and T4 returning their concentrations back to normal and homeostasis is achieved.

6.      Solve for FTI if TT4 = 10 mg/dL, and THBR = 20%

FTI = TT4 X THBR

FTI = 10 X (20/30)

FTI = 6.67 mg/dL

7.      Two methods for T3.T4 test

RIA, EMIT, EQUILIBRIUM DIALYSIS ,ETC.
