FNDH 400 final Actual Exam Questions
and CORRECT Answers
T/F: Compared to amylopectin, amylose is branched and contains alpha-1-6 bonds at its
branch points. - CORRECT ANSWER- ✔✔False. Compared to amylose, amylopectin is
branched and contains alpha-1-6 bonds at its branch points.
T/F: Compared to amylopectin, an oligosaccharide is longer and contains less prevalent alpha
1-6 bonds. - CORRECT ANSWER- ✔✔False. Compared to amylopectin, an oligosaccharide
is shorter and contains more prevalent alpha 1-6 bonds.
T/F: Compared to amylopectin, glycogen is more branched, and also has alpha 1-6 bonds at
its branch points. - CORRECT ANSWER- ✔✔True
T/F: Trans fatty acids have lower melting points than cis fatty acids, meaning trans fatty acids
are more likely to be liquid at room temperature. - CORRECT ANSWER- ✔✔False. Cis fatty
acids have lower melting points than trans fatty acids, meaning cis fatty acids are more likely
to be liquid at room temperature.
T/F: In individuals with PKU, since proline cannot be converted to tryptophan because of the
mutation in proline hydroxylase, tryptophan is conditionally essential in these individuals. -
CORRECT ANSWER- ✔✔False. In individuals with PKU, since phenylalanine cannot be
converted to tyrosine because of the mutation in phenylalanine hydroxylase, tyrosine is
conditionally essential in these individuals.
T/F: Individuals with PKU need to consume a high protein diet and avoid consuming the
amino acid advantame, because it can be broken down to the amino acid proline. -
CORRECT ANSWER- ✔✔False. Individuals with PKU need to consume a low protein diet
and avoid consuming the alternative sweetener aspartame, because it can be broken down to
the amino acid phenylalanine.
T/F: A product that contains inulin (oligofructose) and bifidobacterium could be considered a
symbiotic. - CORRECT ANSWER- ✔✔True
,T/F: In the stomach, pancreatic lipase and amylase digest lipid and protein, respectively. -
CORRECT ANSWER- ✔✔False. In the stomach, gastric lipase and pepsin digest triglyceride
and protein, respectively.
T/F: Since high-fructose corn syrup contains free fructose, it will result in more fructose
being available for uptake and absorption than sucrose. - CORRECT ANSWER- ✔✔False.
High-fructose corn syrup contains free fructose, it will result in approximately the same
amount fructose being available for uptake and absorption than sucrose.
T/F: A limiting amino acid is an essential amino acid that is present in inadequate amount in a
protein preventing it from being a complete protein. - CORRECT ANSWER- ✔✔True
T/F: Heartburn results from a leaky pyloric sphincter, which allows gastric fluid to enter the
duodenum. - CORRECT ANSWER- ✔✔False. Heartburn results from a leaky lower
esophageal sphincter, which allows gastric fluid to enter the esophagus.
T/F: Maramus results from inadequate protein, but adequate caloric intake and is
characterized by an extended abdomen. - CORRECT ANSWER- ✔✔False. Kwashiorkor
results from inadequate protein, but adequate caloric intake and is characterized by an
extended abdomen.
T/F: Complementary proteins provide the essential amino acid found in inadequate amounts
in the other protein, thus complementing one another. - CORRECT ANSWER- ✔✔True
T/F: Fermentable, viscous fiberis readily excreted in feces and also increases stool bulk and
transit time thus decreasing constipation and colon cancer risk. - CORRECT ANSWER-
✔✔False. Nonfermentable, nonviscous fiber is readily excreted in feces and also increases
stool bulk and transit time thus decreasing constipation and colon cancer risk.
T/F: Mannitol (a sugar alcohol), is a poor option for use in products like chewing gum
because it is readily fermented by bacteria in the mouth, decreasing acid production, and thus
reducing cavities. - CORRECT ANSWER- ✔✔False. Mannitol (a sugar alcohol), is a good
option for use in products like chewing gum because it is not fermented by bacteria in the
mouth, decreasing acid production, and thus reducing cavities.
, T/F: Glucose is the sweetest monosaccharide, while fructose is seldom found free in nature. -
CORRECT ANSWER- ✔✔False. Fructose is the sweetest monosaccharide, while galactose
is seldom found free in nature.
T/F: Maltose is a complex carbohydrate of glucose-galactose bonded together with a beta
bond. - CORRECT ANSWER- ✔✔False. Maltose is a simple carbohydrate of glucose-
glucose bonded together with an alpha bond.
T/F: Eicosanoids produced from essential omega-6 fatty acid longic acid elongated fatty acids
are less inflammatory than those produced from the essential omega-3 fatty acid beta-
longeleic acid elongated fatty acids. - CORRECT ANSWER- ✔✔False. Eicosanoids
produced from essential omega-3 fatty acid alpha-linolenic acid elongated fatty acids are less
inflammatory than those produced from the essential omega-6 fatty acid linoleic acid
elongated fatty acids.
Name the macronutrient that is not digested to any great extent in the stomach. - CORRECT
ANSWER- ✔✔carbohydrates
The table below shows hypothetical results for the relationship between daily intermittent
fasting and cancer risk. The period or intake is during what period of time each day does a
person consume food/calories. A quartile is splitting a group into 4 (1 is the lowest, 4 the
highest quartile).
A) Indicate the risk for the quartiles in the "Risk Indicated" column (2 points): For significant
quartiles, type significant increase or significant decrease For non-significant quartiles, type
non-significant increase or non-significant decrease
B) What can you say about the impact of intermittent fasting on cancer risk and how it should
be practiced by someone interested in it based off these results (2 points)? - CORRECT
ANSWER- ✔✔QuartilePeriod of IntakeOdds Ratio (OR) 95% CIRisk Indicated
1: 6 hours 0.77 (0.54-0.99) Significant decrease
2: 8 hours 0.92 (0.78-1.18) Non-significant decrease
3: 10 hours 1.18 (1.00-1.38) Non-significant increase
4: 12 hours 1.25 (0.99-1.49) Non-significant increase
B) Based off the table the lower amount of hours you have between daily intermittent fasting
the lower risk of cancer. With the lowest amount of hours, 6 hours between fasting had a
significant decrease in cancer risk and the 8 hour period also had a decrease even though it
was not significant. Once the time period between fasting periods reached 10 hours we see a
slight increase, but not a significant one.
