The primary integration center in the brain for hormonal systems and neural
systems that regulate food intake for the digestive tract is the
a. Hypothalamus
b. Thalamus
c. Hindbrain
d. Cerebellum - CORRECT ANSWER-a. Hypothalamus
The kidney plays an important role in water conservation. More water is
extracted from collecting ducts of the kidney and returned into the
circulation when stimulates the insertion
of aquaporins into the cell membrane
a. Calcitriol
b. EPO
c. PTH
d. Vasopressin (ADH) - CORRECT ANSWER-d. Vasopressin (ADH)
All of the following are promoters of calcium absorption from the GI tract
except?
,2

We obtain vitamin D from ultraviolet light from the sun converting a form of
cholesterol to cholecalciferol in the skin. It is then metabolized into the most
biologically active form which is called
a. 25-dihydroxcholesterol
b. 25-methyl cholecalciferol
c. 1,25-dihydroxycholeaclciferol
d. 1,24,25 trihydroxycholesterol - CORRECT ANSWER-c. 1,25-
dihydroxycholeaclciferol
Vitamin K acts as a cofactor for an enzyme that catalyzes the carboxylation of
glutamic acid. The carboxylation results in the conversion of glutamic acid to
gamma-carboxyglutamic acid. Which Vitamin K vitamer would you expect to be
responsible for the greatest portion of this activity for a vegetarian
a. menaquinone
b. menadione
c. phylloquinone
d. phyllodione - CORRECT ANSWER-c. Phylloquinone
Osteoblasts are cells responsible for formation of bone vitamin K....
a. inhibits osteoclasts
b. activates osteoblasts
c. is a cofactor for modification of bone protein by osteoblasts
d. causes the calcium concentration to be high enough to precipitate in the
bone. - CORRECT ANSWER-c. is a cofactor for modification of bone protein
by osteoblasts
Low blood calcium causes release of PTH from the parathyroid gland. If Vitamin
D were deficient in that case, which of the following would be least likely to
occur?
, 4
a. The PTH will activate calbidin D synthesis in the duodenum to increase
calcium absorption
b. The PTH will stimulate release of calcium and phosphate from bone.
c. The PTH will stimulate greater calcium reabsorption from the kidney tubule
fluid.
d. Serum levels of PTH would remain more elevated than if vitamin D were
adequate - CORRECT ANSWER-a. The PTH will activate calbidin D synthesis in
the duodenum to increase calcium absorption
