NUSC 1165 Exam 2 questions well
answered already passed
Where does energy production from nutrients occur in our cells? What pathway produces the
most ATP? - correct answer ✔✔Energy Production: In the Mitochondria
Pathway: Glycolysis
What foods are good sources of unrefined complex carbohydrates? Unrefined simple
carbohydrates? - correct answer ✔✔Unrefined complex carbohydrates: legumes, whole grains,
bread
Unrefined simple carbohydrates: fruits, vegetables, milk, sugar cane, anything that ends in -ose
What are the differences between refined flour and unrefined flour? - correct answer ✔✔-
Refined flour is separated from natural vitamins, minerals and fiber, made largely from
endosperm and are mostly starch
-Unrefined flour has bran, germ, and endosperm
What is the basic unit of carbohydrate? - correct answer ✔✔Monosaccharides (single sugar
unit)
How are bonds between monosaccharides formed? Broken? - correct answer ✔✔-
Monosaccharides are formed by condensation or dehydration reaction. condensation reactions
release a molecule of water by taking a hydroxyl group from one sugar and a hydrogen atom
from the other
, -Monosaccharides are broken by a chemical reaction that breaks the bonds between sugar
molecules. Hydrolysis reactions use water to add a hydroxyl group (OH) to one sugar and a
hydrogen atom (H) to the other.
List three common simple carbohydrates. Where are they found in the diet? Where are they
found in the body? - correct answer ✔✔-Glucose: found in table sugar, found in blood
-Galactose: found in dairy products, found in tissues
-Fructose: found in fruit, found in the liver and insulin
Why is added sugar considered a source of empty kcalories? - correct answer ✔✔Added sugar
add calories but no nutrients
Why does a diet high in sucrose promote tooth decay? - correct answer ✔✔When sugar is
consumed it interacts with the bacteria within the plaque to produce acid. This acid is
responsible for tooth decay because it slowly dissolves the enamel creating holes or cavities in
the teeth.
List the different types of complex carbohydrates and where they are found in food. - correct
answer ✔✔-Oligosaccharides: formed in the gut, found in beans, legumes, onions, bananas,
artichoke, and garlic
-Starches: accumulates in roots and tubers. found in vegetables and grains, sweet potatoes,
beets, turnips, potatoes, legumes
-Fiber: not found in body because they cannot be digested. Food sources include wheat bran,
rye bran, fruits, vegetables, whole grains
-Glycogen: don't consume in our food
