UIUC MCB 246 Final Exam Questions With Complete
Solutions
(HPb-HPif)-(COPb-COPif) Correct Answers What is the NFP
formula
4 globin proteins (2 alpha and 2 beta chains), 1 iron and heme
group per globin Correct Answers Structure of hemoglobin
Acromegaly Correct Answers excessive GH during adulthood
after epiphyseal plates have ossified; bone widening
Addison's disease Correct Answers insufficient production of
steroids (adrenal cortex hormones)
ADH Correct Answers What regulates reabsorption of H2O
into the collecting system via a concentration gradient
ADH Correct Answers which hormone level increases when
dehydrated and controls urine output so that we remain
hydrated; concentrates urine and conserves water; sends signals
to thirst center; causes formation of water channels to allow for
more reabsorption of water from tubular filtrate
Adrenocorticotropic hormone Correct Answers targets the
adrenal glands and stimulates the adrenal cortex to release
corticosteroids
Aldosterone Correct Answers which hormone level changes
depending on plasma concentration; it increases Na channels
,and Na/K pumps in tubules to increase Na reabsorption and
expel K
All organic nutrients; ions (Na+, K+, Cl-, Ca2+, Mg2+) and
bicarbonate, water, amino acids, urea, and glucose Correct
Answers What is reabsorbed in the PCT
ANP Correct Answers which hormone level increases when
overhydrates; opposite of ADH; lowers blood pressure by
stimulating kidneys to increase urine output and for blood
vessels to dilate; decreases water and Na+ reabsorption
Anterior pituitary Correct Answers Where is GH produced
arterial end of capillaries Correct Answers Where does filtration
occur
atrial contraction and ventricular filling + atrial relaxation and
ventricular filling Correct Answers When is the AV valve open
but the semilunar valve closed
Atrial fibrillation Correct Answers chaotic timing of atrial
action potentials
atrial repolarization (hidden by QRS complex) Correct Answers
What is not visible on an ECG
AV node Correct Answers action potential is delayed
, Biconcave, anucleated, flexible, with many hemoglobin Correct
Answers What is the anatomy of an erythrocyte?
Blood colloid osmotic pressure (OPg) Correct Answers osmotic
pressure from suspended proteins in blood; opposes filtration
(draws water out of filtrate)
Blood colloid osmotic pressure Correct Answers caused by
suspended proteins in blood that are too large to cross capillary
walls
Bradycardia Correct Answers abnormally slow heart rate; <60
bpm
by antigens on the surface of RBC Correct Answers How is
blood type determined
Calcitonin Correct Answers decreases blood calcium levels
(decrease osteoclast activity in bone)
Capillary hydrostatic pressure Correct Answers
Capsular hydrostatic pressure (HPc) Correct Answers resistance
to flow along nephron and conducting system; opposes
glomerular hydrostatic pressure (pushes water and solutes out of
filtrate)
CD markers Correct Answers The molecular mechanism of
antigen recognition
