CORRECT ANSWERS
What enzyme that releases fatty acids from triglycerides in the mouth? - Answer-lingual
lipase
What enzyme that releases fatty acids from triglycerides in the stomach? - Answer-
gastric lipase
What enzyme that releases fatty acids from triglycerides in the small intestine? -
Answer-pancreatic lipase
Explain why the enzyme that digests lipids ar produces as pro-prancratic lipase and pro-
phospholipase A2 - Answer-the enzyme that digests lipids are produced in their inactive
forms to prevent premature digestion
Why doesn't the pancreas produce pancreatic amylase in an inactive form? - Answer-
because its activity does not pose a risk of damage to the pancreas
What is the name of an enzyme produced in an inactive form? - Answer-zymogen
Lipid Digestion, Absorption and assimilation once fattya acids and glycerol have been
absorbed into the inetstsinal epithelial cell please describe everything that occurs prior
to their entrance into the blood - Answer-
Name the first substrate and last product:
Glycolysis - Answer-glucose, pyruvate
Name the first substrate and last product:
gluconeogenesis - Answer-pyruvate, glucose
Name the first substrate and last product:
glycogenesis - Answer-glucose, glycogen
Name the first substrate and last product:
glycogenolysis - Answer-glycogen, glucose
fasting activated pathways in the liver? - Answer-gluconeogenosis, glucogenosis, TCA
, why can gastric lipase exist and have function in the stomach? - Answer-proteins are
usually consumed with lipids and the buffer ph of the stomach
why are pancreatic lipase and phospholipase A2 are made as zymogens? - Answer-so
they don't act on TAGs or phospholipids In the pancreas where they are produced
define zymogen - Answer-enzyme produced in inactive form
where does beta-oxidation occur in the cell? - Answer-mitochondria
where does lipogenesis occur in the cell? - Answer-cytosol
why is beta-oxidation called beta-oxidation? - Answer-oxidizes the beta-carbon
