A cell is incubated with a radioactive lipid called [3H]-palmitic acid. Membrane proteins are then isolated from the cell using multiple different treatments. High pH and high salt treatments serve to reduce the strength of ionic and hydrogen-bonding interactions. Determine the type of membrane protein that is isolated from each of these treatments.
