EEOB Exam 4 Practice Questions and
Answers
What does the protein act like in carrier mediated transport? What type of protein is used? -
ANSWER-a shuttle (integral transmembrane protein)
What regulates carrier mediated transport? Why? - ANSWER-binding regulates transport because
the solute mus...
In facilitated diffusion, what causes the transport? How? - ANSWER✔✔-conformation change of the
protein caused by the solute binding into the protein
What is saturation in facilitated diffusion? How does this happen? - ANSWER✔✔-overloading of solutes;
caused by the transporter only being able to move a set number of solutes at once
What can speed up the facilitated diffusion process? Will this always cause it to go faster than it was? -
ANSWER✔✔-a larger gradient of solutes can speed up the process, but it will level out at some point
(causing saturation if solutes keep building up)
How do competitors work with facilitated diffusion (different types)? - ANSWER✔✔-competitors will
either activate the transporters themselves (not being the ligand that usually goes through it) or it will
block the transporter (which may stop the process by not allowing movement)
What is a glucose transporter (GLUT) an example of? - ANSWER✔✔-facilitated diffusion
How do solutes move in active transport (as an overall)? - ANSWER✔✔-almost always against the
gradient
Is there an energy cost with active transport? Why or why not? - ANSWER✔✔-there is an energy cost
because the solutes are traveling against the gradient
What does the conformation changes in active transport cause? - ANSWER✔✔-transport and ATP use
What are the two types of active transport? - ANSWER✔✔-primary and secondary AT
