RATED CORRECT WITH 100% SURE
PASS|GRADED A+
The adequate intake for carbohydrates is ______ grams per day. - CORRECT ANSWERS 130
What is the daily carbohydrate intake range (in grams) that corresponds to a 50-60% carbohydrate, 2000
calorie diet? - CORRECT ANSWERS 250-300
Which of these fibers is soluble? - CORRECT ANSWERS 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 __________.
- CORRECT ANSWERS 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? -
CORRECT ANSWERS Glycolysis
In the absence of oxygen, muscle contraction is sustained by the glycolytic system.
Primary sugar in milk - CORRECT ANSWERS lactose
Which organ relies solely on glycolysis for energy? - CORRECT ANSWERS 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? - CORRECT ANSWERS
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? - CORRECT
ANSWERS 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? - CORRECT ANSWERS
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? - CORRECT ANSWERS 45-75 grams
Touch the fatty acid that would form a SOLID fat at room temperature. - CORRECT ANSWERS
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.
Which of these dairy foods is highest and lowest in total fat? - CORRECT ANSWERS Butter
and Skim Milk
Skim milk (0%). Reduced Fat (2.5%) Whole milk (3.5%). Half and half (10%). Butter (80%)
The predominant fatty acids in coconut oil, butter, and lard are _____. - CORRECT ANSWERS
All three of these dietary fats are highly SATURATED, meaning they are comprised of carbon chains
without double bonds. When saturated fatty acids are concentrated, at room temperature, solid fats
form.
