Introduction to nutrition

Question 1

What is nutrient balance

Answer 1

Change in body stores of certain nutrients

Question 2

When is the body able to better the ability to withstand further changes of a nutrient

Answer 2

When it has bigger stores

Question 3

What can occur as a result of a change in nutrient balance

Answer 3

Overnutrition and undernutrition

Question 4

What is nutrient turnover

Answer 4

Metabolic substrates are continually being utilised and replaced which allows for rapid adjustments to changes in metabolic states.

Question 5

What is nutrient flux

Answer 5

Measure of the activity of the metabolic pathway

Question 6

What is nutrient flux not necessarily related to

Answer 6

Size of the metabolic pool

Question 7

Which nutrients have faster nutrient flux

Answer 7

Those with smaller metabolic pathways

Question 8

What is nutrient flux more to do with

Answer 8

Size of the particular pathway

Question 9

What are functional pools

Answer 9

Direct involvement in body functions (eg in the case of glucose in body, this would be glucose)

Question 10

What are storage pools

Answer 10

Provides buffering effect i.e. can be made available to the functional pool when and as required (in the case of glucose in body, would be liver and muscles)

Question 11

What are precursor pools

Answer 11

Provides the substrate for nutrient/metabolite synthesis (in the case of glucose, it would be amino acids)
