Use the image to answer the following questions 1. Does glucose transport across the apical membrane require ATP (i.e., is it active or passive)? Why or why not? 2. Based on energy requirements, how would you classify this transporter: facilitated diffusion, primary active, secondary active, simple diffusion, vesicular 3. Based on physical requirements, how would you classify this transporter: carrier-mediated, channel protein, vesicle uniporter or co-transporter (symporter or antiporter) 4. What is the function of this transporter? (I.e., what is it moving and where from and to?).
