FNDH 620 UPDATED ACTUAL FINAL PAPER QUESTIONS
AND SOLUTIONS GUARANTEE A+
✔✔allosteric regulation - ✔✔When a enzymes function at one site is affected by the
binding of a regulatory molecule to a separate site.
✔✔Non-competitive inhibition - ✔✔when one substrate or inhibitor changes the
structure of of the enzyme stopping the other from binding, inhibiting decreases the
speed of the reaction
✔✔Can glucokinase or hexokinase be inhibited by allosteric means? - ✔✔Only
hexokinase
✔✔What is the key enzyme in glycogenolysis? - ✔✔glycogen phosphorylase
✔✔What are two allosterically regulated enzymes that found in the skeletal muscle? -
✔✔hexokinase and phosphofructokinase
✔✔In glycogenolysis, when does glucose become free glucose? (Dephosphorylated) -
✔✔after it goes to the liver, only organ (kidney can but not much) that can
dephosphorylate glucose
✔✔In the process of cleaving glucose from glycogen (glycogenolysis) to lactic acid, how
many ATP are produced and why this number? - ✔✔3, this is because glycogenolysis
only spends 1 atp in the first step, so after it makes 4 atp, it has a total of three atp
made
✔✔What occurs in the entry step for the Krebs cycle? - ✔✔Pyruvate loses a carbon,
becomes acetyl CoA
✔✔Why do we need oxaloaceatate from glucose? - ✔✔Without a steady supply we
wouldn't not be able to repeat the Krebs cycle
✔✔What is the overall reaction products from the Krebs cycle? - ✔✔3 NADH, 1 FADH2,
and 1 ATP (Times 2)
✔✔Which foods are abundant in pectin? - ✔✔fruits
✔✔What kind of fibers may apply to healthy protection against heart disease? -
✔✔viscous fibers
✔✔What are the products of secondary metabolism in plants? - ✔✔Secondary
metabolites
, ✔✔The content of phytochemical in plants are variable, usually increased in response
to environmental stress? TF? - ✔✔True
✔✔According to the Dietary Supplement & Health Education Act of 1994, you need
these two statements for nutraceuticals. - ✔✔It has not been evaluated by the FDA and
it is not intended to diagnose cure or treat diseases
✔✔Why do phytochemicals protect against chronic disease? - ✔✔non conclusive, but
may include, anti-oxidants, inhibition of cell growth and if nutrient absorption, induction
of apopitiosis, stimulation of the immune system.
✔✔What are two major dietary carbs? - ✔✔Disaccharides and Straches
✔✔To prevent accumulation of ketone bodies, a tissue cell must have a functioning... -
✔✔Krebs cycle
✔✔(T/F) The major precursors for gluconeogenesis are lactate, glycerol and certain
amino acids. - ✔✔True
✔✔What statement about pyruvate is most accurate? - ✔✔Pyruvate is the main
precursor to oxlaacetate
✔✔What is not true about glucokinase? - ✔✔insulin inhibits glucokinase
✔✔Does hemicellulose consist of cellulose and polysaccharides? - ✔✔No
✔✔What is the effect of decreased blood glucagon to insulin ratio on the activity of the
Cori Cycle? - ✔✔Decreased
✔✔Is lingin a carb? - ✔✔No
✔✔ What is the purpose of coupling metabolic reactions? - ✔✔to enable an
endothermic reaction to become exothermic
✔✔What is the role of NADH and FADH2 in the ETC? - ✔✔to transfer electrons, which
creates a gradient for the pump, creating ATP in the process
✔✔What are the four layers of the Small Intestine? (In order of innermost to outermost)
- ✔✔mucosa, submucosa, muscularis, and serosa
✔✔Between the villi and microvilli, which aids in digestion? - ✔✔microvilli
✔✔What absorbs nutrients in the small intestine? - ✔✔enterocytes
