Verified
Structure of protein - correct answer composed of carbon, hydrogen, oxygen, and nitrogen and
arranged as strands of amino acids
Three components of amino acids - correct answer amine group, acid group, side chain
How many essential amino acids exist? - correct answer 9
Why are adequate amounts of all essential amino acids required for protein synthesis? - correct
answer without essential amino acids the body can't make the proteins that it needs to do
work
What factors differentiates protein? - correct answer ...
7 roles of protein in the body - correct answer support growth and maintenance, building
enzymes and hormones and other compounds, building antibodies, maintaining acid base
balance, transport substances, maintaining fluid and electrolyte balance, and energy.
In the stomach - correct answer acid denatures the protein strands, and an enzyme cleaves
amino acid strands into polypeptides and a few amino acids
In the small intestine - correct answer enzymes from pancreas and intestine split peptide
strands into tripeptides, dipeptides and amino acids
enzymes on intestine surface lining split tripeptides and dipeptides. the intestinal cells absorb
and transfer amino acids into blood stream
Bloodstream - correct answer carries amino acids to the liver where they are used or released
into the blood to be taken up by other cells of the body
Nitrogen balance study - correct answer compare nitrogen lost by excretion to the nitrogen
eaten in food, consumed compared to excreted in a time period.
measure losses through urine, feces, sweat, and skin
Nitrogen balance - correct answer Nitrogen balance=
Nintake-(Nurine+Nsweat+Nfeces+Nskin)
Mutual supplementation (aka complementary proteins) - correct answer combining two
incomplete protein sources so that the amino acids in one food can make up for those lacking
in other food
Vegetarian meal plans containing complementary proteins - correct answer without meat.
additional servings of milk, bread, and eggs will help add to your servings of protein. Grains and
AA of legumes go together

vessels, seen in protein deficiency
Limiting amino acid - correct answer essential amino acid that is present in dietary protein in an
insufficient amount, limiting the body's ability to build protein
high-quality protein - correct answer containing all essential amino acids that are required but
may contain non-essential
positive nitrogen balance - correct answer growing children add new blood, bone, and muscle
cells to their body everyday meaning they have more protein and nitrogen by the end of they
day
(child, pregnant woman, someone building muscle)
negative nitrogen balance - correct answer when muscle or other protein tissue is broken down
and lost
(astronaut, surgery patient)
