UTA NURS 5315 Test 1 Questions andComplete Solutions Graded A+
byproduct of aerobic metabolism - Answer: carbon dioxide (CO2)
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. cancer cellular division is unregulated and malignant cells can invade local or
distant tissues
Are cancer cells specialized? - Answer: No, only normal cells are specialized
Are cancer tumors encapsulated? - Answer: No, only benign tumors are encapsulated.
