Facilitated diffusion is different from simple diffusion because it:
Moves molecules against the concentration gradient
Uses carrier proteins
Requires ATP
Occurs only in plant cells

What are the aquaporins in facilitated diffusion process?
    Membrane proteins
Carrier proteins
Channel proteins
Carrier lipids
If two molecules A & B move in the same direction. This movement can be called
Antiport
Symport
Uniport
Guttation
Choose odd one out w.r.t. facilitated diffusion.
Highly selective
Uphill and needs ATP
Transport achieves saturation
Affected by protein inhibitors
Which statement can be shared by facilitated diffusion and active transport?
    Both need carrier transporter, which are sensitive to inhibitors that reacts with protein side chains
    Energy is required by both the processes
    No energy expenditure in these processes
Both use carbohydrates to move molecules
across the membrane
    Water channels are possessed by a membrane to facilitate the movement of hydrophilic substances.
These channels are made up of
Proteins
Lipids
Carbohydrates
Nucleic acids
In facilitated diffusion, saturation occurs when:
The concentration gradient disappears.
All carrier proteins are occupied by the transported substance.
The cell runs out of ATP.
The temperature decreases significantly.
    Select the wrong statement regarding membrane channels
    They are proteins
They are usually gated, i.e., may be open or closed
    All ions pass through the same type of channel
    They form a huge pore in the outer membrane of plastids, mitochondria and some bacteria
Certain integral membrane proteins facilitate the diffusion of molecules across the membrane without directly binding to the transported molecule. These proteins create a continuous aqueous pathway through the lipid bilayer. Which of the following is the BEST example of such facilitated diffusion?
GLUT transporters moving glucose
Sodium-potassium pump maintaining ion gradients
Aquaporins transporting water
Chloride channels gated by voltage
Facilitated diffusion involves?
Downhill transport
Without expenditure of energy
Involvement of proteins
All
Active transport
    Releases energy
Requires energy
Produces ATP
Produces a toxic substance
