NST 103 Midterm 1 Exam 2025
Questions and Answers
alpha 1,4 - ANSWER✔✔-amylose contains this type of glycosidic bond
cholesterol - ANSWER✔✔-bile salts are formed from this type of common lipid species
monosaccharides - ANSWER✔✔-High concentrations of _____________ in the gut
lumen will induce GLUT2 trafficking to the apical membrane
GLUT2 - ANSWER✔✔-A low-affinity (high Km) glucose transporter in hepatocytes and
pancreatic cells that serves as the glucose sensor for insulin release
endoplasmic reticulum - ANSWER✔✔-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) - ANSWER✔✔-the proteins that FFAs
bind to to cross the plasma membranes
, dietary fiber - ANSWER✔✔-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 - ANSWER✔✔-sodium-glucose cotransporter for shuttling monosaccharides
secondary active transport - ANSWER✔✔-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 - ANSWER✔✔-the transport of substances through a cell
membrane along a concentration gradient with the aid of carrier proteins (ex: GLUT)
GLUT - ANSWER✔✔-move glucose and related hexose sugars across membranes
trypsin - ANSWER✔✔-an enzyme from the pancreas that digests proteins in the small
intestine. Also is responsible for the activation of Colipase and Phospholipase A2
colipase - ANSWER✔✔-protein secreted by pancreas that binds lipase, bringing it in
contact with lipid droplets in the small intestine
phospholipase A2 - ANSWER✔✔-enzyme that splits arachidonic acid from plasma
membrane phospholipids
gastric lipase - ANSWER✔✔-enzyme that is responsible for the breakdown of
triacylglycerol (TAG) in the stomach
