EXAM QUESTIONS WITH
CORRECT DETAILED
ANSWERS | GRADED A+

QUESTION; Where does transcription occur - ANSWER-cytoplasm


QUESTION; what are the three types of RNA - ANSWER-messenger RNA,
transfer RNA, ribosomal RNA


QUESTION; byproduct of aerobic metabolism - ANSWER-carbon dioxide
(CO2)


QUESTION; what enzyme converts CO2 to Carbonic acid H2CO3 -
ANSWER-carbonic anhydrase


QUESTION; _________ is a byproduct of anaerobic metabolism of
glucose - ANSWER-lactic acid

,QUESTION; end product of oxidation of sulfur containing amino acids -
ANSWER-sulfuric acid


QUESTION; end product of metabolism of phosphoproteins and
ribonucleotides which are used as an energy source - ANSWER-
phosphoric acid


QUESTION; __________ binds with 40% of calcium - ANSWER-albumin


QUESTION; charge of albumin - ANSWER-negative


QUESTION; 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


QUESTION; 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


QUESTION; When the extracellular fluid volume is expanded it
____________ the reabsorption of HCO3 in the ____________
___________ - ANSWER-inhibits; proximal tubule

, QUESTION; A deficit in ECF volume results in a __________ in the
reabsorption of HCO3 - ANSWER-increase


QUESTION; What hormone does ECF volume deficit stimulate -
ANSWER-RAAS


QUESTION; How does RAAS affect bicarb - ANSWER-Angiotension II
stimulates the Na-H exchanger in the proximal tubule --> increases
HCO3 reabsorption


QUESTION; 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


QUESTION; Where does the renal excretion of hydrogen occur? -
ANSWER-distal tubule and collecting ducts


QUESTION; What 2 active transport system are used to secrete H -
ANSWER-H-ATPase and H-K-ATPase


QUESTION; 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
