- potassium
- magnesium
Solution
Analyze the Question
The question asks about the role of gastric acid in the absorption of certain nutrients.
Relevant Concepts
Gastric acid, primarily composed of hydrochloric acid (HCl), is crucial for the digestion of food and the absorption of various nutrients. It creates an acidic environment that facilitates the breakdown of food and aids in the absorption of certain minerals.
Answer:
Among the options provided:
- Iron: Gastric acid is important for the absorption of iron, particularly in its non-heme form, by converting it to a more soluble form.
- Copper: Gastric acid also aids in the absorption of copper, but its role is less significant than that of iron.
- Potassium and Magnesium: While they are also important minerals, their absorption is less dependent on gastric acid compared to iron.
Final Answer:
Iron is the nutrient for which gastric acid plays the most crucial role in absorption.
