NTR 419 Exam 1 UPDATED Exam
Questions and CORRECT Answers
Define "essential nutrients" - CORRECT ANSWER - Nutrients that are necessary for life
but we cant make enough of them so we have to get them exogenously.
What are all the macronutrients? - CORRECT ANSWER - 1.)Water
2.)Protein
3.) Carbs
4.) Lipids
5.) Sterols
Why is water important and what are some ways you can lose water? - CORRECT
ANSWER - Important because you can suffer from dehydration
Acute loss: exercise, vomiting, diarrhea, dieresis
Chronic loss: inadequate intake, decrease thirst sensistivity
What is protein status and why is it important? - CORRECT ANSWER - The amount of
protein in the body and is important as a predictor of morbidity and mortality.
What is the golden standard amount of protein that should be in the body? - CORRECT
ANSWER - No golden standard but serum albumin levels are most often used as a marker
for protein status.
What can happen if someone has low serum albumin status? - CORRECT ANSWER - 1.)
primary cause of morbidity and mortality because of low immune function
2.) secondary to something else; therefore is a marker
Define "conditionally essential" - CORRECT ANSWER - Non-essential that becomes
essential due to some condition
, Define non-dietary amino acids . - CORRECT ANSWER - Produced during amino acid
metabolism
What are some simple sugar monosaccharide carbohydrates? - CORRECT ANSWER - 1.)
Glucose
2.)Fructose
3.) Galactose
What are some simple sugar disaccharide carbohydrates? - CORRECT ANSWER - 1.)
Lactose
2.) maltose
3.) Sucrose
Which carbohydrate is the most abundant monosaccharide? - CORRECT ANSWER -
Glucose
What are some functions of glucose? - CORRECT ANSWER - 1.) primary fuel for the
brain and CNS
2.) becomes primary fuel during acute stress
(all of which affects protein status)
What can happen if someone has excess dietary glucose? - CORRECT ANSWER - 1.)
Converted to glycogen: in the liver and sent to muscles for storage. Some stored in the liver
2.) Converted to fat: in the liver and goes to adipose tissue for storage.
What is the fate of fructose in the body? - CORRECT ANSWER - 1.) can be metabolized
by some cells for energy
(must be converted to glucose or fat in the liver; concerns for high fructose corn syrup)
