1. Food containing chlorophyll are a source of which mineral?

Na

Mg

Cl

P

2. The distribution of sodium and potassium ions between intracellular and
extracellular compartments is...

sodium mainly intracellular, potassium mainly in extracellular

equal amounts of both ions, in both intracellular and extracellular
fluids

potassium mainly intracellular, sodium mainly in extracellular

little of either intracellular but large amounts of both extracellular

3. Which water-soluble vitamin can regenerate vitamin E after it has been
oxidized?

vitamin B12

folate

vitamin C

vitamin D

,4. If a person has a deficiency in vitamin D, what impact might this have on their
calcium levels and bone health?

, It will have no effect on calcium levels or bone health.

It will increase calcium absorption and strengthen bones.

It may lead to decreased calcium absorption and increased risk of
bone health issues.

It will cause calcium to be stored in excess in the bones.

5. Which form of vitamin D is primarily found in fortified foods and plant-based
sources?

Calcidiol

Vitamin D2

Vitamin D3

Calcitriol

6. This small protein binds 4 calcium ions, undergoes a significant structural
change on binding calcium, and then proceeds to interact with other target
proteins to mediate many calcium effects.

Calmodulin

Parvalbumin

Ras

CaM KII

Troponin C

7. If a patient presents with hypocalcemia and is found to have low magnesium
levels, what would be a recommended course of action?

Increase dietary calcium without addressing magnesium levels.

Supplement magnesium to improve calcium levels.

, Prescribe vitamin D only to increase calcium absorption.
