UTA NURS 5315 TEST 1 WITH THE
LATEST SCORE.
Byproduct of aerobic metabolism - Correct Answer-carbon dioxide (CO2)
What enzyme converts CO2 to Carbonic acid H2CO3 - Correct Answer-
carbonic anhydrase
_________ is a byproduct of anaerobic metabolism of glucose - Correct
Answer-lactic acid
End product of oxidation of sulfur containing amino acids - Correct Answer-
sulfuric acid
End product of metabolism of phosphoproteins and ribonucleotides which are
used as an energy source - Correct Answer-phosphoric acid
__________ binds with 40% of calcium - Correct Answer-albumin
Charge of albumin - Correct Answer-negative
What happens with albumin and calcium in acidotic states - Correct 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 - Correct 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 ____________ ___________ - Correct Answer-
inhibits; proximal tubule
, A deficit in ECF volume results in a __________ in the reabsorption of HCO3 -
Correct Answer-increase
What hormone does ECF volume deficit stimulate - Correct Answer-RAAS
How does RAAS affect bicarb - Correct 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? - Correct 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? - Correct Answer-distal
tubule and collecting ducts
What 2 active transport system are used to secrete H - Correct Answer-H-
atpase and H-K-atpase
How do the 2 transport systems move H to be excreted - Correct 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? - Correct Answer-
monohydrogen phosphate (HPO4)
What does mono hydrogen phosphate produce - Correct Answer-H2PO4 -->
dihydrogen phosphate
Once H2P04 is created what can happen with it? - Correct Answer-it can be
excreted
What happens to the cell cycle when cancer develops? - Correct Answer-cell
life cycle is unregulated and the cells grow and proliferate. Cancer cellular
division is unregulated and malignant cells can invade local or distant tissues
Are cancer cells specialized? - Correct Answer-No, only normal cells are
specialized
Are cancer tumors encapsulated? - Correct Answer-No, only benign tumors
are encapsulated.
