Explain the significance of each and whether it is an active or passive process.9. Match each of the following statements related to membrane transport processes to the appropriate term: passive transport, facilitated transport, active transport. More than one term may apply in a given situation. _a. Movement across the membrane is against the concentration gradient. _b. Proteins serve as "gates." _c. Expenditure of cellular energy is required. _d. Movement across the membrane is from a high to a low concentration.10. What is osmosis? Is it correct to call it the diffusion of water across a membrane permeable only to the solvent, (water), and impermeable to the solutes?
