HUN2201 Human Nutrition Exam 3 Questions and
Correctly Solved Answers Graded 100% A++
1 ATP yields - CORRECT ANSWER ✔✔ -7 kcals
Biotin - CORRECT ANSWER ✔✔ -Active form: citrate
Functions: fatty acid synthesis and metabolism
Deficiency symptoms/diseases: acetyl CoA carboxylase reactions
Blood Clots - CORRECT ANSWER ✔✔ --Fibrous cap is when a part of the plaque buildup at
the injury site breaks off to form a clot that is made up of fibrin and cholesterol/plaque
-Clot travels through the blood to get stuck at the site connecting the blood vessel to the heart,
which blocks the passageway and leads to lower oxygen levels since no oxygen is being
transported
-Can lead to stroke/infraction (heart attack)
-To help avoid this, consume more omega-3 fatty acids which produce eicosanoids which help
decrease blood clotting
Calculate a goal amount (i.e.- number of pounds) for initial weight loss and a goal weight
(pounds) for initial weight loss. - CORRECT ANSWER ✔✔ --A 10% reduction over 6 months
in body weight reduces risk factors
-Weight should be lost at a rate of 1-2 lbs per week based on a 500-1000 calorie deficit
-ex. if 200 lbs, lose 20 lbs over 6 months to become 180 lbs
,Calculate and interpret BMI (Given: Ht. and Wt.). - CORRECT ANSWER ✔✔ -BMI = kg (wt) /
m2 (ht)
BMI = wt (lb) x 703.1 / ht (in) ^2
Determine the dietary factors that may increase or decrease ones risk for CVD (i.e.- Heart
Healthy Diet). - CORRECT ANSWER ✔✔ -Increase risk:
-Southern Diet: high in sugar and saturated fats
-Low carb diets: increased risk from LDL cholesterol
-High carb diets
-Added Sugars
Decrease risk:
-Mediterranean diet
-DASH diet
-plant based diets
-(these focus on mono and polyunsaturated fats, reduce saturated and trans fats, and focus on
nutrient dense foods and low fat protein sources aka vegetables, fish, eggs, fruits, whole grains)
Endothelial Injury - CORRECT ANSWER ✔✔ -Inflammation (omega-3 fatty acids from fatty
fish and nuts)
-omega-3 produces eicosonoids, which produces PG, which lowers inflammation
Hypertension (increase calcium and potassium, decrease sodium, and exercise)
, -Blood pressure = heart rate x SV(fluidity of blood) x resistance
-We want to decrease blood pressure so we exercise to decrease heart rate
-Reducing sodium causes a decrease in blood volume which decreases blood pressure
-Resistance is the inverse of 1/diameter of an artery so decreasing the diameter causes resistance
to go up
-We want to increase the diameter which decreases resistance
-This is called vasodilation which needs calcium to take place
Homocysteine
-We want to decrease homocysteine levels
-We want to consume folate (found in leafy green vegetables, broccoli, cauliflower) and vitamin
B-12
-This is going to methylate (CH3) homocysteine (bad) which converts it into methionine (good)
Oxidative Stress
-Need to consume antioxidants (really dark green veggies)(Vitamin A, C, E,
phytochemicals)(anything purple and orange and green is really good)
-Reduces oxidative stress
Explain cross sections of a healthy and unhealthy artery - CORRECT ANSWER ✔✔ -Cross-
section of a nice artery has a nice round, pink opening, while a bad artery is reddish with a not
clear opening because it is more clogged with plaque from cholesterol
