Question
An increase in vitamin C intake results in a(n) ______ of excretion of the vitamin by the kidneys.
Multiple choice question.
- decrease
- increase
Solution
Understanding the Concept
Vitamin C, or ascorbic acid, is a water-soluble vitamin. Its solubility affects how the body absorbs and excretes it.
Analyzing Vitamin C Metabolism
- When vitamin C intake increases, the body's absorption mechanism is capable of taking in only a certain amount.
- Once the saturation point is reached, any excess vitamin C that isn't needed by the body will be filtered out by the kidneys.
- This results in an increase in the excretion of vitamin C through urine.
Conclusion
Based on the understanding that excess vitamin C intake leads to increased excretion due to the kidneys filtering out what is not absorbed or needed by the body:
Final Answer
Increase. An increase in vitamin C intake results in an increase of excretion of the vitamin by the kidneys.
