Phospholipid bilayers are NOT stabilised by: a. van der Walls forces b. covalent bonds c. hydrogen bonds d. ionic bonds e. hydrophobic interactions - Answer-b. covalent bonds A transmembrane protein has the following properties: it has two binding sites, one for solute A and one for solute B. The protein can undergo a conformational change to switch between two states: either both binding sites are exposed exclusively on one side of the membrane, or both are exposed exclusively on...
