### Question 11

The red diamond represents an endogenous chemical messenger. Which of the following statements is correct?

#### Diagram Interpretation
The diagram depicts three cells labeled CELL A, CELL B, and CELL C. Each cell has a rectangular shape with a nucleus (represented by a blue circle) inside. There are receptors on the surface of each cell, represented by small yellow structures. The red diamond, denoting an endogenous chemical messenger, interacts with these receptors.

Arrows indicate that the red diamond is binding to the receptors on each of the three cells, suggesting a signaling mechanism.

#### Multiple Choice Options
1. **The ligand is an autocrine signal when it binds to the receptor on CELL A**
2. **The ligand is a hormonal signal when it binds to the receptor on CELL C**
3. **The receptors on CELLS A-C are functionally classified as membrane transport proteins**
4. **The receptors on CELL B and CELL C are different than the receptor on CELL A**

In the context of cell signaling, these options explore different types of signaling mechanisms and the nature of receptors involved in cellular communication.
