Answers | Latest Version 2024 | Verified
What does the protein act like in carrier mediated transport? What type of protein is used? - ✔✔a
shuttle (integral transmembrane protein)
What regulates carrier mediated transport? Why? - ✔✔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? - ✔✔facilitated diffusion and active transport
Which type of carrier mediated transport allows diffusion to happen easier? - ✔✔facilitated diffusion
Does active transport use diffusion? Why or why not? - ✔✔it does not use diffusion because it is going
against the gradient
How is glucose typically brought into cells? - ✔✔Through facilitated diffusion
Is there an energy cost with facilitated diffusion? Why or why not? - ✔✔there is not an energy cost
because it is going with the gradient
In facilitated diffusion, what causes the transport? How? - ✔✔conformation change of the protein
caused by the solute binding into the protein
What is saturation in facilitated diffusion? How does this happen? - ✔✔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? -
✔✔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)? - ✔✔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? - ✔✔facilitated diffusion
How do solutes move in active transport (as an overall)? - ✔✔almost always against the gradient
Is there an energy cost with active transport? Why or why not? - ✔✔there is an energy cost because the
solutes are traveling against the gradient
What does the conformation changes in active transport cause? - ✔✔transport and ATP use
What are the two types of active transport? - ✔✔primary and secondary AT
Which type of active transport uses ATP directly? - ✔✔primary AT
What are ATPase pumps? Where are they used (directly)? - ✔✔an ATPase pump is an enzyme that
breaks down ATP; makes gradient; used directly in primary AT
What equation does primary AT use directly? - ✔✔equation 1
How many substances can be moved through primary AT at a time? - ✔✔one or two DIFFERENT
substances
Does secondary AT use ATP? If so, how? - ✔✔yes, uses ATP indirectly
Why does secondary AT use ATP indirectly? - ✔✔it relies on Primary AT to make the gradient (with the
ATPase pumps) to power secondary AT
