NUTRITION AND DIET EXAM 2
QUESTIONS WITH VERIFIED
ANSWERS. A+ GRADE 2025/2026.
Trace the digestion of carbohydrates through the gastrointestinal tract by arranging the steps
of chemical digestion of a piece of bread beginning when you take your first bite. -
ANS Salivary amylase breaks down amylose and amylopectin in the bread into smaller
chains.
Step 2
Carbohydrate-digesting enzymes are inactivated by hydrochloric acid.
Step 3
Pancreatic amylase breaks down amylose and amylopectin into the disaccharide maltose.
Step 4
Dissacharides are digested by the brush border enzymes sucrase, maltase, and lactase to yield
monosaccharides.
Step 5
Dietary fiber from the bread passes into the large intestine to be eliminated.
The alpha bonds of carbohydrates are broken down during digestion by specific enzymes.
Lactose contains a beta bond, which is digestible by lactase. Most carbohydrates that contain
beta-glycosidic bonds are not digestible because humans lack the enzyme needed to break
down the bond. Which of the following carbohydrates contain alpha bonds that are digestible
by humans? - ANS amylose and amylopectin

, Which of the following statements correctly describes the process of carbohydrate absorption?
- ANS Glucose and galactose are absorbed into the enterocyte by active transport before
they enter the capillaries for transport through the bloodstream.
Which of the following statements best describes the role of dietary fiber in reducing the risk of
developing diseases? - ANS Soluble fibers slow the digestion and release of glucose
preventing a spike in blood glucose following a meal. This increase in transit time may improve
long-term control of diabetes.
How is digestion altered in individuals who have been diagnosed with lactose intolerance? -
ANS Undigested lactose draws water into the gastrointestinal tract, causing diarrhea and
cramping.
How many total kilocalories are in Ella's sandwich? - ANS 544
How many total grams of carbohydrate are in Ella's sandwich? How many grams of fiber? How
many grams of total and added sugars? When you are asked to provide a set of two or more
numeric answers, separate them with commas. Round your answer to the nearest whole
number. - ANS Total Carbohydrates, Dietary Fiber, Total Sugars, Added Sugars: 48, 4, 8, 4 g
What is the percentage of kilocalories from carbohydrates in Ella's sandwich? Round your
answer to the nearest whole percent (for example, 12 - ANS 35%
Does Ella's sandwich meet the AMDR recommendation for carbohydrate? - ANS No
Ella understands that the AMDR is meant to assess a day's worth of food intake and not just
one item, such as a sandwich, but she frequently makes this sandwich for lunch and wants to
determine what she could do to make this lunch more closely meet the AMDR for carbohydrate
and the Dietary Guidelines for Americans related to carbohydrates.Which of the following
would be the best change to bring Ella's lunch in line with the AMDR and the Dietary Guidelines
for Americans for carbohydrates? - ANS adding an apple to her meal
