### Question:

Which of the following amino acids are most likely to be present on the surface of Protein A in the picture below?

### Diagram Description:

The image depicts a segment of a cell membrane with a protein labeled "Protein A" embedded in it. The membrane consists of a double layer of lipids. The illustration shows a lipid bilayer with hydrophilic (pink) heads facing outward and hydrophobic (green) tails in the center. Protein A extends beyond the lipid bilayer into the external environment.

### Answer Options:

- F-M-A-Y-I-L
- S-E-R-T-D-K
- G-L-S-M-A-I
- P-G-G-T-F-W

### Explanation:

The amino acids that are most likely to be on the surface of Protein A are those that are hydrophilic or charged, as they commonly interact with the aqueous environment outside the membrane.
