QUESTION 1 All assignments will revolve around the case study theme for the unit. This unit's theme is sickie cell anemia - see the previous assignment for some details about siokle cell anemia. The main role of hemoglobin is to transport oxygen. Red blood cells use hemoglobin to pick up oxygen from the lungs and then drop it off at subsequent cells. Red blood cells also carry sugar (glucose) around the body. Glucose is picked up in the stomach and dropped off subsequent cells. When an ndividual has sickle cell anemia, blood does not flow properly and oxygen and sugar are not transported effectively The first 5 questions are "scavenger hunts". You should be able to find the answers in your notes. When red blood cells reach muscles, oxygen will move across the plasma membrane into the cell. Remembering that axygen is small and non-polar, how will it enter the cell? Facilitated Diffusion Simple Diffusion Osmosis Active Transport QUESTION 2 is moved from blood into other cells using a carrier protein and facilitated diftusion. Which of the following is TRUE of camier proteins during facilitated diffusion? They do not change shape during the transport of solutes They require energy to push solutes against the gradient The carrier proteins only span the membrane one time They can be saturated if the number of carnier proteins is equal to or less than the number of sokutes to be transported

Explanation / Answer

1. Facilitated transport

2. they require energy to push the solutes against the gradient.

3. the substrates

4. delta G decreases

5. binding affinity between enzymes and substrates.

6. ATP is directly hydrolysed by glucose transporter to move sodium out of the cell

7. Vmax

9. Reversible and non- competitive inhibitor
