UTA NURS 5315 TEST 1 STUDY GUIDE 2026
QUESTIONS WITH VERIFIED ANSWERS
GRADED A+
◉ what enzyme converts CO2 to Carbonic acid H2CO3. Answer:
carbonic anhydrase
◉ _________ is a byproduct of anaerobic metabolism of glucose.
Answer: lactic acid
◉ end product of oxidation of sulfur containing amino acids.
Answer: sulfuric acid
◉ end product of metabolism of phosphoproteins and
ribonucleotides which are used as an energy source. Answer:
phosphoric acid
◉ __________ binds with 40% of calcium. Answer: albumin
◉ charge of albumin. Answer: negative
◉ what happens with albumin and calcium in acidotic states.
Answer: There is an increased amount of H ions which causes
,albumin to bind to more H ions and less calcium ions causing
calcium ions to become displaced leading to a higher level of free
calcium
◉ what happens with albumin and calcium in alkalotic states.
Answer: There is a decreased amount of H ions causing a insufficient
amount of H ions to bind with albumin. This causes albumin to bind
with more calcium (due to H depletion) and causes a decreased
amount of free calcium
◉ When the extracellular fluid volume is expanded it ____________ the
reabsorption of HCO3 in the ____________ ___________. Answer: inhibits;
proximal tubule
◉ A deficit in ECF volume results in a __________ in the reabsorption of
HCO3. Answer: increase
◉ What hormone does ECF volume deficit stimulate. Answer: RAAS
◉ How does RAAS affect bicarb. Answer: Angiotension II stimulates
the Na-H exchanger in the proximal tubule --> increases HCO3
reabsorption
◉ Angiotension II stimulates the Na-H exchanger in the proximal
tubule --> increases HCO3 reabsorption --> what does this cause?.
, Answer: metabolic alkalosis (contraction alkalosis) secondary to
volume depletion- can occur with use of loop/thiazide diuretics
◉ Where does the renal excretion of hydrogen occur?. Answer:
distal tubule and collecting ducts
◉ What 2 active transport system are used to secrete H. Answer: H-
ATPase and H-K-ATPase
◉ How do the 2 transport systems move H to be excreted. Answer:
move H into the lumen and move potassium from the lumen into the
cells
◉ once H is in the lumen what does it bind with?. Answer:
monohydrogen phosphate (HPO4)
◉ what does mono hydrogen phosphate produce. Answer: H2PO4 --
> dihydrogen phosphate
◉ once H2P04 is created what can happen with it?. Answer: it can
be excreted
◉ what happens to the cell cycle when cancer develops?. Answer:
cell life cycle is unregulated and the cells grow and proliferate.
