Question 1. Which direction can small molecules, such as sugars and amino acids, are transported?
Question 2. How does the sugar move? How does the concentration of sugar compare inside and outside of the cell?
Question 3. How is this transport of sugar driven through a coupled transport protein? Are these counterions moving from a higher to lower concentration or from a lower to higher concentration?
Question 4. What is symport? Why occurs there?
Question 5. How is a low concentration of sodium maintained inside the cell? How is it powered?
Question 6. What is counter-transport?
Question 7. What is an antiport? What occurs there? How is this different that what occurs at a symport?
Question 8. How does the sodium-potassium pump come into play in this process?
