Q11

**Membrane Transport Education Module**

This module includes a selection-based activity designed to help learners understand different types of membrane transport mechanisms.

### Activity Instructions

For each statement below, select the appropriate substance that corresponds with the described transport mechanism:

1. `[ Select ]` would move across a membrane using **simple diffusion**.
2. `[ Select ]` would move across a membrane using **primary active transport**.
3. `[ Select ]` would move across a membrane using **secondary active transport**.

### Available Options

- **Glucose (when blood glucose is high)**
- **Glucose (when blood glucose is low)**
- **Sodium ions**
- **Carbon dioxide**

### Explanation of Transport Mechanisms

1. **Simple Diffusion**: This occurs when molecules pass directly through the cell membrane without energy input, typically following a concentration gradient from high to low concentration. Example: Movement of carbon dioxide.

2. **Primary Active Transport**: This involves the direct use of metabolic energy (ATP) to transport molecules against their concentration gradient. Example: Sodium ions via sodium-potassium pump.

3. **Secondary Active Transport**: This type of transport uses the energy from the electrochemical gradient created by primary active transport to move substances. Example: Glucose absorption in the intestines when blood glucose is low.

Use the dropdown menus to select the correct substance for each transport type based on their typical biological behavior.
