1) Movement of solutes from a low to a high concentration (requires energy) a) Simple diffusion b) Active transport c) Facilitated diffusion d) Osmosis 2) Movement of solutes from a high to a low concentration (does not require energy) a) Active transport b) Facilitated diffusion c) Simple diffusion d) Osmosis 3) What happens to ATP when it is used fo active transport? a) Condensation reaction b) Hydrolysis reaction c) ADP + Pi --> ATP d) ATP --> ADP + Pi  e) ATP hydrolase needed f) ATP synthase needed 4) What type of carrier protein binds to two molecules at the same time? a) Channel protein b) Peripheral protein c) Extrinsic protein d) Co-transporter e) Integral protein 5) This transports Sodium ions out of the ileum and into the blood whilst transporting potassium out of the blood and into the ileum a) Sodium - phosphorus pump b) Na+ /K+  Pump c) Sodium Glucose cotransporter d) Protein channel e) Carrier protein f) Sodium Potassium pump 6) In the ileum, a cotransporter protein.... a) Transports sodium and glucose into the epithelial cell b) Transports sodium down its concentration gradient c) Transports sodium against its concentration gradient d) Transports Sodium and potassium into the epithelial cell e) Transports glucose down its concentration gradient  f) Transports glucose against its concentration gradient 7) Factor's that make active transport quicker include.... a) Slower rate of cellular respiration b) Low number of protein carriers c) High number of protein carriers d) Faster working protein carriers e) Slower working protein carriers f) Faster rate of cellular respiration to produce ATP 8) Unlike facilitated diffusion, active transport does not use... a) Carrier proteins b) Channel proteins c) Pumps
