Answer the following questions (please cite your textbook orother reference you use, no wikis please)
1. Skeletal muscle cells produce glucose carriers (GLUT 4transporters). Rather then having these transporters continually ontheir surface, they store them inside vesicles within the cell.During exercise (muscular contraction), these vesicles fuse withthe plasma membrane of the cell, inserting the transporters intothe membrane. This allows glucose to enter the cell by passivetransport. Which of the factors that affect simple diffusion hasbeen altered in this example?
2. Recall the chemiosomotic synthesis of ATP occurring inside themitochondria. Would you expect to measure an electrical potentialacross the inner membrane of the mitochondria when chemiosmosis isactive? Why or why not? If so, which compartment in themitochondria would have a more positive charge?
Please answer the specific questions no need for additionalinformation.
