1. byproduct of aerobic metabolism carbon dioxide
(CO2)
2. what enzyme converts CO2 to Carbonic acid H2CO3 carbonic anhy-
drase
3. is a byproduct of anaerobic metabolism of lactic acid
glucose
4. end product of oxidation of sulfur containing amino sulfuric acid
acids
5. end product of metabolism of phosphoproteins and phosphoric acid
ribonucleotides which are used as an energy source
6. binds with 40% of calcium albumin
7. charge of albumin negative
8. what happens with albumin and calcium in acidotic There is an in-
states creased amount of
H ions which caus-
es albumin to bind
to more H ions
and less calci-
um ions causing
calcium ions to
become displaced
leading to a higher
level of free calci-
um
9. what happens with albumin and calcium in alkalotic There is a de-
states creased amount
of H ions caus-
ing a insufficient
amount of H ions
to bind with al-
bumin. This caus-
es albumin to bind
, UTA NURS 5315 Test 1 with Verified Answers
with more calci-
um (due to H de-
pletion) and caus-
es a decreased
amount of free cal-
cium
10. When the extracellular fluid volume is expanded inhibits; proximal
it the reabsorption of HCO3 in the tubule
11. A deficit in ECF volume results in a in the increase
reabsorption of HCO3
12. What hormone does ECF volume deficit stimulate RAAS
13. How does RAAS affect bicarb Angiotension II
stimulates the
Na-H exchanger
in the proximal
tubule --> increas-
es HCO3 reab-
sorption
14. Angiotension II stimulates the Na-H exchanger in the metabolic alkalo-
proximal tubule --> increases HCO3 reabsorption --> sis (contraction
what does this cause? alkalosis) sec-
ondary to volume
depletion- can oc-
cur with use of
loop/thiazide di-
uretics
15. Where does the renal excretion of hydrogen occur? distal tubule and
collecting ducts
16. What 2 active transport system are used to secrete H H-ATPase and
H-K-ATPase
17.
, UTA NURS 5315 Test 1 with Verified Answers
How do the 2 transport systems move H to be excret- move H into the
ed lumen and move
potassium from
the lumen into the
cells
18. once H is in the lumen what does it bind with? monohydrogen
phosphate
(HPO4)
19. what does mono hydrogen phosphate produce H2PO4 --> dihy-
drogen phosphate
20. once H2P04 is created what can happen with it? it can be excreted
21. what happens to the cell cycle when cancer devel- cell life cycle is un-
ops? regulated and the
cells grow and
proliferate. can-
cer cellular divi-
sion is unregulat-
ed and malignant
cells can invade
local or distant tis-
sues
22. Are cancer cells specialized? No, only normal
cells are special-
ized
23. Are cancer tumors encapsulated? No, only benign tu-
mors are encap-
sulated.
