The following are sensitive to inhibitors

Options

A. Uniporters
B. Symporters
C. Antiporters
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which transport mechanisms are sensitive to inhibitors. The options provided are uniporters, simporters, antiporters, or all of the above.

2. **Defining Uniporters**: A uniporter is a type of transport protein that facilitates the movement of a single type of ion or molecule across the cell membrane. This process can be sensitive to inhibitors that affect the transport mechanism.

3. **Defining Simporters**: A simporter is a transport protein that moves two different ions or molecules in the same direction across the cell membrane. Like uniporters, simporters can also be affected by inhibitors.

4. **Defining Antiporters**: An antiporter is a transport protein that carries two different ions or molecules in opposite directions across the cell membrane. Antiporters are also sensitive to inhibitors.

5. **Conclusion**: Since all three types of transport mechanisms (uniporters, simporters, and antiporters) are sensitive to inhibitors, the correct answer is option D: all the above.

**Final Answer**: Option D: all the above.
