✓ DetailsDraw a protein that is embedded in a membrane (a transmembrane protein), label the lipid bilayer and the protein. Identify the areas ofthe lipid bilayer that are hydrophobic and hydrophilic.Draw a membrane with two transporters: a proton pump transporter that uses ATP to generate a proton gradient, and a secondtransporter that moves glucose by secondary active transport (cartoon-like is ok). It will be important to show protons moving in thecorrect direction, and that the transporter that is powered by secondary active transport is logically related to the proton pump.
