Question

1. Transmembrane proteins are embedded in cell membranes. If one transmembrane protein is pulled away from the cell membrane using a magnetic force microscope, and the force required to extract this protein is: fIpN)-15(x/nm)+(x nm) where r is the distance between the protein and membrane. The protein is pulled from the fully embedded state (x 0) to fully unbound state (x2-5 nm) 1.1 What is the work needed to extract this transmembrane protein? 1.2 What would be the work (in Joule) needed to extract 1 mole of such transmembrane protein?
