NTRI 2000 EXAM 3 2025 QUESTIONS
AND ANSWERS
Nitrogen - ANS Unlike carbs and fats, proteins contain:
4 - ANS Proteins provide _kcal/gm?
Amino Acids - ANS What form are is essential nitrogen stored as?
regulate and maintain - ANS Proteins _______ and _________ body functions.
Amino Acids - ANS What are the building blocks of protein?
9 - ANS How many essential amino acids are there?
Infancy - ANS Needs for protein are highest during:
11 - ANS How many nonessential (can be synthesized by the body) amino acids are there?
Must be supplied by the diet and is needed for daily bodily functions. - ANS Essential
branched chain amino acids. - ANS Isoleucine, Leucine, and Valine are:

, fueling muscles during activity - ANS what are branched chain amino acids used for?
the amino acid that is in the shortest supply in the diet in relation to body needs. - ANS What
is the limiting amino acid?
proteins. - ANS when amino acids bond, ________ are formed.
peptide bond. - ANS the bond between amino acids is a:
protein synthesis - ANS DNA contains coded instructions for ________ _________ within the
nucleus of the cell.
cytoplasm of the cell - ANS Where does protein synthesis occur?
mRNA - ANS a transcribed segment of DNA that is transferred to the cytoplasm is:
transcription. - ANS the process from DNA to mRNA is:
shape. - ANS the order of the amino acids in a protein determines its:
disease. - ANS if the amino acid sequence is mutated, the final shape is disrupted, causing:
one amino acid changes, like glutamic acid to valine. It occurs on two of the subunits, and
creates a change in protein organization, which creates the disease state. This causes the
hemoglobin to contain 4 subunits. - ANS What causes sickle cell anemia?
decrease in oxygen to cells, severe pain in joints/bones, headaches, abdominal pain,
convulsions, and paralysis. - ANS What are the symptoms of sickle cell anemia?
