Question

11. Synthesis of ATP using the energy released as a proton diffuses down a concentration gradient involves the conversion of concentration gradient energy into chemical energy—True or false?

12. In the absence of active transport of a molecule, a simple or facilitated diffusion of the molecule will result in an equilibrium of the molecule across the membrane—True or false?

13. In the absence of an active transport of a molecule, a simple or facilitated diffusion of the molecule across a membrane will result in zero energy available to do work—True or false?

14. If biological membranes were permeable to all solutes osmosis could not occur because the concentration of water will be same on both sides of the membrane—True or false?
