Carrier ions like `Na^(+)` faciltate the absorption of substance like

Options

A. amino acids, and glucose
B. glucose and fatty acids
C. fatty acids and glycerol
D. fructose and some amino acids.

Explanation

To answer the question regarding which substances are facilitated in absorption by carrier ions like sodium ions (Na+), we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Understanding Carrier Ions**:
- Carrier ions, such as sodium ions (Na+), play a crucial role in the absorption of various substances in the intestines.

**Hint**: Remember that carrier ions help transport other molecules across cell membranes.

2. **Identifying Substances Absorbed by Sodium Ions**:
- The primary substances that are absorbed with the help of sodium ions are glucose and amino acids.

**Hint**: Think about the major macromolecules that our body needs and how they are absorbed.

3. **Mechanism of Absorption**:
- Glucose is absorbed through a specific co-transporter known as the sodium-glucose co-transporter (SGLT-1). This transporter facilitates the absorption of glucose along with sodium ions into the intestinal epithelium.

**Hint**: Focus on the specific transporters that are involved in the absorption process.

4. **Amino Acids Absorption**:
- Similarly, amino acids are absorbed via sodium amino acid co-transporters. Each class of amino acid has its own specific co-transporter that works alongside sodium ions.

**Hint**: Consider how different types of amino acids might require different transport mechanisms.

5. **Evaluating Options**:
- Given the options provided, the correct answer is the one that includes both glucose and amino acids, as they are both absorbed using sodium ions.

**Hint**: Cross-check the options against the substances you identified that are absorbed with the help of sodium ions.

### Final Answer:
The correct substances that are facilitated in absorption by carrier ions like sodium ions (Na+) are **glucose and amino acids**.
