Question 6 (1 point)

Choose all of the following that are characteristics of facilitated membrane transport.

Question 6 options:

permeability increases with the permeability of individual transporters

is the name given to the transport that dissipates the gradient that forms another gradient

permeability increases with increasing number of transporters

would direct net Na+ transport into a typical human cell

permeability increases with the permeability of individual transporters

is the name given to the transport that dissipates the gradient that forms another gradient

permeability increases with increasing number of transporters

would direct net Na+ transport into a typical human cell

Explanation / Answer

Answer.

1. Permeability increases with the permeability if individual transporter. It is because facilitated diffusion is a gradient based process dependent on specific transporters. The more permeability of transporters, more transport occurs.

2. It does not dissipate the gradient and forms reversal or another gradient as the process becomes saturated with time and stops when gradient disappears.

3. The permeability increases with increasing number of transporters. This is because, Facilitated diffusion is concentration and transporter dependent and depends on number of transporters.

4. It is not necessary that net transport occurs into a cell as it depends on concentration.
