NDFS 100 EXAM 2 (CHAPTER 5-7) STUDY GUIDE
Transamination - Answer -Moving the amino or nitrogen group
Deamination - Answer -
Protein digestion - Answer -1: Nothing
2: Acid denatures
3: Acid Neutralized, di-, tri-peptides, aa
4: Breakdown of amino acid, absorption of aa
5: AA----liver
Which is true about protein digestion and absorption? - Answer -Proteins are broken
down into individual amino acids and absorbed in the small intestine.
Roles of protein - Answer -Structure, regulation, energy, growth and development,
antibodies, blood clotting, enzymes & hormones, transporters, fluid and electrolyte
balance.
Positive Nitrogen balance - Answer -adding tissue ( a growing child, a pregnant
woman, building muscle)
Nitrogen Equilibrium - Answer -equal in and out (a healthy college student)
Negative Nitrogen Balance - Answer -losing tissue, excreting more than you digested.

High quality protein
Mid-range protein
Lower-quality protein - Answer -Meat
Legumes
Grains
AMDR for Protein - Answer -10-35% of calories
RDA (DRI) for protein - Answer -.8 g/kg
135 lbs, what is the RDA? - Answer -48 g
(135/2.2= 60
Brandon weighs 165 lbs. What is his RDA for protein? - Answer -60 g
(165/2.2= 75
75x.8= 60 g)
, What is false regarding protein supplements? - Answer -Eating a protein supplement
without physical exercise will
Protein is wasted when - Answer -Insufficient energy intake, excess protein intake,
excess single amino acid, too few essential amino acids.
Inadequate Protein Intake - Answer -usually deficient in energy and other nutrients,
health consequences (growing decreases diseases resistance goes down, susceptibility
to infections goes up, edema (swelling), kidney and heart problems, apathetic, listless)
Extra amino acid - Answer -Competes for absorption
Celiac Disease - Answer -autoimmune response to protein in wheat, barley, and rye
Villi are flattened and detroyed, reducing nutrient absorption (biopsy)
Celiac Disease Cause - Answer -Genetic component and trigger (stress, trauma or
possible viral infection
Celiac Disease Symptoms - Answer -nausea, vomiting, diarrhea, reduced growth in
children (malabsorption)
Celiac Disease Diagnosis - Answer -Not on the basis of symptoms, blood tests and
intestinal biopsy (get diagnosis 1st)
Celiac Treatment - Answer -life-long avoidance of gluten-containing foods: wheat,
barley, and rye (any products made from them)
Benefits to Vegetarian Diets - Answer -less obesity/chronic diseases
high fiber, fruits, and vegetables
less saturated fats
Pitfalls of vegetarianism - Answer -low energy
low minerals (Ca, Fe, Zn), vitamin B-12 and Vitamin D
What makes protein different from other macronutrients? - Answer -Protein contains
nitrogen
Needed for body to synthesize protein - Answer -adequate amount of energy and
protein
all essential amino acids in the proper amounts
NOT needed for body to synthesize protein - Answer -all essential amino acids
consumed at the same time
Complementary proteins - Answer -Tofu (soy beans) and rice, combined give all amino
acid
