a) Count the number of non-polar and polar amino acids in each of the separate sections of the protein which is within the lipid bilayer. Record your values in a suitable table and calculate the ratio of non-polar:polar amino acids. lipid bi-layer
b) Repeat this process for each of the sections of the protein which lie outside the lipid bilayer. inside cell
c) How does the ratio of non-polar:polar amino acids differ between a) and b)? Explain why this might be the case.
