⩥ 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.
