NTR 555 Exam 1 Questions with Correct
Answers
In- vs dispensible nutrient✔✔indispensi: not synthizable (leu)
dispensiple: synthizable (glu
complex vs simple carb✔✔complex: highly branched poly saccarides (starch)
simple: mono/di sac
cori cycle (glycolisis)✔✔glycolysis is a component of cori, muscel takes glu runs it thro glycolisis
-if pyruvate dehydro is shut down shuttle pyruvate to lactate and goes back to the muscle to become glu
again
cortisol / insulin✔✔-stress hormone or elevates bld glu
-insulin dec bld glu
gluconeogenesis/glyco✔✔-creates glu from end products of glycolysis (on when
-creates glycogen from glu
glucose alanine cycle✔✔during exercise glu syn to alanine to use other sub and reuses the N in the liver
to make urea
glycogen loading (super compensation) same✔✔maximizes storage of glycogen before an athletic event
(moderate to high carb diet
hypoglycemia✔✔hypo: low bld glu concen
hyper: high bld glu concen
, acetyl CoA✔✔-lipid/FA via oxidation makes this
-glu via glycolisis and pyruvate dehydroge makes..
-several AA makes..
-Acetyl CoA goes to TCA for CO2
chylomicron (Gut)✔✔transports lipids, cholesterol and Triglys starting out as a protein and binds to
those (lipoprotein, VLDL-liver)
Epinephrine Hormone sensitive lipase✔✔(adrenaline) E triggers hormones like hormone sensitive lipase
to cleave 1st FA from Trigly in fat tissue
lipoprotein lipase✔✔target tissues where u need FA from TG in lipoprotein
long chain FA (short/medium)✔✔short produce by bac in gut
medium food portal vein directly into tissue
long abs by chylomicron
PUFA (poly unsat FA) liquid✔✔some are essential
NEFA (non-esterfied FA)✔✔free FA, when fat cells brkdwn TG release free FA into tissue so it may be
abs
trans FA (hydrogenated) solid
solid fat (sat/hydrogenated) solid✔✔processed, not too much
3-methylhistidine✔✔modified AA, doesnt get recycled but get excretted. brkdwn muscle prot u will
excrett more of this so this can be measured
