NST 103 MIDTERM 1QUESTIONS AND VERIFIED
ANSWERS, 100% GUARANTEE
alpha 1,4 - amylose contains this type of glycosidic bond
cholesterol - bile salts are formed from this type of common lipid species
monosaccharides - High concentrations of _____________ in the gut lumen will induce
GLUT2 trafficking to the apical membrane
GLUT2 - A low-affinity (high Km) glucose transporter in hepatocytes and pancreatic cells
that serves as the glucose sensor for insulin release
endoplasmic reticulum - fatty acid binding proteins (FABP-I and FABP-L) are responsible
for binding and transporting fatty acids to here; also the site of prechylomicron formation
fatty acid binding proteins (FABP-I and FABP-L) - the proteins that FFAs bind to to cross
the plasma membranes
dietary fiber - Lowered serum cholesterol levels, delayed gastric emptying, interference
with nutrient absorption, and improved glucose tolerance are all effects of this in the stomach
and small intestine
SGLT - sodium-glucose cotransporter for shuttling monosaccharides
secondary active transport - Form of active transport which does not use ATP as an
energy source; rather, transport is coupled to ion diffusion down a concentration gradient
established by primary active transport. (ex: SGLT)
facilitated diffusion - the transport of substances through a cell membrane along a
concentration gradient with the aid of carrier proteins (ex: GLUT)
, GLUT - move glucose and related hexose sugars across membranes
trypsin - an enzyme from the pancreas that digests proteins in the small intestine. Also is
responsible for the activation of Colipase and Phospholipase A2
colipase - protein secreted by pancreas that binds lipase, bringing it in contact with lipid
droplets in the small intestine
phospholipase A2 - enzyme that splits arachidonic acid from plasma membrane
phospholipids
gastric lipase - enzyme that is responsible for the breakdown of triacylglycerol (TAG) in
the stomach
linoleic acid - arachidonic acid is synthesized from this essential polyunsaturated fatty
acid of the omega-6 family
eicosanoids - arachidonic acid is used as a precursor to synthesize these
prebiotics - nondigestible starches that promote the growth of intestinal bacteria
glucose - the form of sugar that circulates in the blood and provides the major source of
energy for body tissues
amylose - a polysaccharide found in plants as one of the two components of starch
(making up approximately 20-30% of the structure)
sucrose - glucose + fructose
