NUTR 313: The Nutrients: Exam 2 questions with
complete solutions
The adequate intake for carbohydrates is ______ grams per day. - ANSWER-
130
What is the daily carbohydrate intake range (in grams) that corresponds
to a 50-60% carbohydrate, 2000 calorie diet? - ANSWER-250-300
Which of these fibers is soluble? - ANSWER-Pectin
Cellulose, lignan and resistant starch are all insoluble fibers, whereas
pectin is a type of soluble fiber
Starch to polysaccharide digestion begins in the _________ and fibers are
fermented in the __________. - ANSWER-mouth, large intestine
Starch to polysaccharide digestion happens primarily in mouth and
fibers are fermented in large intestine
In the absence of oxygen, muscle contraction is sustained by what
glucose-dependent energy system? - ANSWER-Glycolysis
In the absence of oxygen, muscle contraction is sustained by the
glycolytic system.
Primary sugar in milk - ANSWER-lactose
Which organ relies solely on glycolysis for energy? - ANSWER-brain
, The brain exclusively uses glucose for respiration, and while only around
2% total body weight, this high-energy organ uses up to 20% of the
glucose that is consumed daily
Gastrointestinal bacteria metabolize resistant starches to yield what
organic acid? - ANSWER-Butyric acid
is an organic acid produced by bacterial fermentation of the indigestible,
resistant starch passing though
Which of these carbohydrate status measures is most likely to elicit
frequent urination? - ANSWER-Hyperglycemia
causes the kidneys to release more water in efforts to rid the blood of
excess sugars.
Long-term carbohydrate status can be evaluated by what measure? -
ANSWER-Glycosylated hemoglobin
The percentage of hemoglobin that is glycosylated is an indicator of long-
term carbohydrate control.
What is the approximate range in daily fat intake (in grams) that
corresponds to a 20-35% fat, 2000 calorie diet? - ANSWER-45-75 grams
Touch the fatty acid that would form a SOLID fat at room temperature. -
ANSWER-The straight carbon chain would more readily form a solid fat.
The kinked chain will not pack as tightly together, and therefore, at room
temperature, would more readily form a liquid fat.
