HUN 1201 PROTEIN EXAM QUESTIONS
WITH COMPLETE ANSWERS
Transamination - ANSWER-the transfer of an amino group from one amino acid to a
keto acid, producing a new nonessential amino acid and a new keto acid
The DRI for protein is________ to________ percent of kcalories. - ANSWER-10-35
percent
The RDA for an adult is ________ gram per kilogram of healthy body weight. -
ANSWER-0.8 grams
Why is the shape of protein important? - ANSWER-The shape enables protein to
perform different functions in the body.
Describe the storage of proteins. - ANSWER-There is no storage form of protein. It is
used directly for energy when needed.
Describe the process of deamination. - ANSWER-stripped of nitrogen-containing amino
group; typically occurs when an excess of protein is consumed
Describe the process of transamination. - ANSWER-transfer of an amino group from
one amino acid to a keto acid which produces a new nonessential amino acid and a
new keto acid.
Describe nitrogen balance and give examples of positive, negative, and equilibrium
nitrogen balances. - ANSWER-the amount of nitrogen consumed as compared with the
amount of nitrogen excreted in a given period of time; positive= more Nitrogen coming
in that out; negative= more Nitrogen going out then coming in; equilibrium is the equal
number of Nitrogen coming out
Describe high-quality protein. - ANSWER--contain all essential amino acids
-proteins derived from animal foods (mean, poultry, fish, eggs, milk)
-Soy protein (tofu)
Describe complementary proteins. - ANSWER--two protein-rich foods combined to
obtain all the essential amino acids in amounts sufficient to support health
-Rice and Beans
Plant foods typically have how many amino acids? - ANSWER-Limited to one or more
amino acids
Vegetarian - ANSWER-general term used to describe an eating pattern that excludes
meat, poultry, fish, or other animal-derived foods from the diet
