Explain different types of membrane transports and give examples of these transports in our body.

7. Which of the following membrane transport proteins would you expect to be the most selective (although not the most rapid)? the bicarbonate ion channel the glucose carrier protein the potassium ion channel the chloride ion channel the sodium ion channel

Match the following statement related to membrane transport processes to the appropriate term or terms: passive transport, facilitated transport, active transport. A transporter (or carrier) protein is necessary. (Select all that apply.) passive transport facilitated transport active transport O O

one reason active transport has a limited maximum transport rate at which it can progress is due to the fact that a. energy required is not available inside the cell b. carrier proteins are not on the surface of the cell membrane  c. ion channels are limited in size d. the number of carrier proteins is limited and therefore they can become saturated

14. Define diffusion, osmosis, facilitated-diffusion, filtration, solute pumps, vesicular/bulk transport, endocytosis, exocytosis, pinocytosis, and phagocytosis. Explain the significance of each and whether it is an active or passive process.

During digestion, the concentration of hydrogen ions (H+) in the stomach rises to many times that within the cells lining the stomach, where H+ are produced. Is the type of transport process involved passive or active?

1 O2 influx _1 Ca2+ influx 3 K+ influx 2 Na+ efflux 1. simple diffusion _1. Na+ influx by itself 2. facilitated diffusion 1 CO2 efflux 3. primary active transport 2 glucose influx by itself 4. secondary active transport 6 steroid influx or efflux 5. endocytosis 3 Ca2+ efflux that consumes ATP 6. eхосytosis 6 efflux of extracellular proteins 4 Na+ influx that occurs with other substances 2 K+ efflux

6- One of the following is an example about the secondary active transport: a- Glucose/ Na* C- H/k b- Kt/Nat d- None of the above

4. In this cartoon, imagine that Romeo is a potassium ion (K+) and Juliet is a sodium ion (Na+). Explain why they're stuck on their own sides of the membrane and what they need to get through it. The Paramecium Parler Wherefore art thou, Ramea?! Star-crossed solutes I'm stuck behind this semipermeable membrane! Ambe Sites
