Intro to Nutrition Flashcards
1
Q
Why are body stores of nutrients important?
A
They have a buffering effect if the body receives less nutrients than needed
2
Q
What is nutrient turnover and why is it important?
A
Nutrients are continually used and replaced, which allows the body to rapidly adjust to new metabolic states
3
Q
What is nutrient flux?
A
A measure of the activity of a nutrient’s metabolic pathway, not necessarily related to size of metabolic pool
4
Q
What are the three types of metabolic pool?
A
Functional, storage, precursor
5
Q
What do each of the metabolic pools do?
A
. Functional pool- used for body functions
. Storage pool- buffering, available to functional pool when needed
. Precursor pool- gives substrates for nutrient and metabolite synthesis
