FNDH 400 Exam 2 questions and answers latest top score. Crypts of Lieberkuhn - correct b/w villi Do crypts contain stem cells true/false - correct Enterocytes a type of cell from the stem cells in crypt mature as you go down more into the crypts true/false - correct answers.False enterocytes mature as the resin or migrate up the villus out of the crypt What happen to enterocytes as they reach the top of the villus - correct answers.They are sloughed off and either digested as lip and protein contain or excreted in feces Absorption is defined as reaching the muscle true/false - correct reaching the body circulation Compounds that are taken up might not necessarily be absorbed because the enterocyte containing the compound might be sloughed off before absorption occurs. true/false - correct At the top of villi are the crypts of Lieberkühn which contain stem cells, many of which differentiate to become enterocytes as they move down the villi, before ultimately being sloughed off. true/false - correct found in the pits between villi, and the enterocytes move up not down villi Which is not a macronutrient digestion product ready for uptake A. glucose B. tripeptide C. 2-monoglycerides D. fatty acids E. sucrose - correct answers.E. sucrose Which is not a protein the thelps move compounds through the phospholipid bilayer cell membrane A. pump B. carrier C. channel D. transporter E. tunnel - correct answers.E. tunnel Active transport does not require energy to move with a concentration gradient true/false - correct answers.False passive does active requires energy to move against the concentration gradient Cleaving a phosphate bond (dephosphorylation) generally releases energy. true/false - correct Osmosis moves solvent instead of solute true/false - correct A solute moving from lower concentration to higher concentration across a membrane is moving with its concentration gradient. true/false - correct moving against its concentration gradient What are the three forms of passive uptake/transport - correct e diffusion, osmosis, facilitated diffusion n simple diffusion, a solute moves from a region with higher solute concentration across a membrane to a region with lower solute concentration with the help of a protein true/false - correct everything is true accept it does not need help from a protein n osmosis, water moves from a region with higher solute concentration across a membrane to a region with lower solute concentration. true/false - correct low concentration to high concentration Facilitated diffusion is like simple diffusion except that a carrier or transport protein is needed to facilitate solute movement across the membrane. true/false - correct Active carrier transport and facilitated diffusion both use a carrier or transport protein, but active carrier transport uses energy and moves with the concentration gradient. true/false - correct moves against the concentration gradient A compound that is endocytosed is taken into the cell in vesicles formed from the cell membrane. true/fals - correct Match each term with the correct thing it is taken up by A. Monosachcarides B. Glucose/Galactose C. Fructose 1. SGLT1 2. GLUT5 3. enterocyte - correct answers.A-3 B-1 C-2
