EEOB Exam 4 Practice Questions and
Answers 100% Pass


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 must interact with the protein,

changes the protein's shape


What are the two types of carrier mediated transport? - ANSWER✔✔-

facilitated diffusion and active transport


Which type of carrier mediated transport allows diffusion to happen

easier? - ANSWER✔✔-facilitated diffusion


Does active transport use diffusion? Why or why not? - ANSWER✔✔-it

does not use diffusion because it is going against the gradient


How is glucose typically brought into cells? - ANSWER✔✔-Through

facilitated diffusion

,Is there an energy cost with facilitated diffusion? Why or why not? -

ANSWER✔✔-there is not an energy cost because it is going with the

gradient


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


Which type of active transport uses ATP directly? - ANSWER✔✔-primary

AT


What are ATPase pumps? Where are they used (directly)? - ANSWER✔✔-

an ATPase pump is an enzyme that breaks down ATP; makes gradient;

used directly in primary AT
