Answers for Specific Exam Mail
byproduct of aerobic metabolism
Ans: carbon dioxide (CO2)
what enzyme converts CO2 to Carbonic acid H2CO3
Ans: carbonic anhydrase
_________ is a byproduct of anaerobic metabolism of glucose
Ans: lactic acid
end product of oxidation of sulfur containing amino acids
Ans: sulfuric acid
end product of metabolism of phosphoproteins and ribonucleotides which
are used as an energy source
Ans: phosphoric acid
__________ binds with 40% of calcium
Ans: albumin
charge of albumin
Pretest - Stuvia US
,2
Ans: negative
what happens with albumin and calcium in acidotic states
Ans: 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
Ans: 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 ____________ ___________
Ans: inhibits; proximal tubule
A deficit in ECF volume results in a __________ in the reabsorption of HCO3
Ans: increase
What hormone does ECF volume deficit stimulate
Ans: RAAS
How does RAAS affect bicarb
Ans: Angiotension II stimulates the Na-H exchanger in the proximal tubule -->
increases HCO3 reabsorption
Pretest - Stuvia US
, 3
Angiotension II stimulates the Na-H exchanger in the proximal tubule -->
increases HCO3 reabsorption --> what does this cause?
Ans: metabolic alkalosis (contraction alkalosis) secondary to volume
depletion- can occur with use of loop/thiazide diuretics
Where does the renal excretion of hydrogen occur?
Ans: distal tubule and collecting ducts
What 2 active transport system are used to secrete H
Ans: H-ATPase and H-K-ATPase
How do the 2 transport systems move H to be excreted
Ans: 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?
Ans: monohydrogen phosphate (HPO4)
what does mono hydrogen phosphate produce
Ans: H2PO4 --> dihydrogen phosphate
once H2P04 is created what can happen with it?
Ans: it can be excreted
what happens to the cell cycle when cancer develops?
