Why the line-with-gaps model is not suitable to explain facilitated diffusion?
Facilitated diffusion is a carrier-mediated form of transport across a membrane. The line-with-gaps model doesn't show the carrier proteins that are in the cell membrane. These proteins are what help facilitated diffusion occur.
What is the process When proteins help molecules move across the membrane is called?
when proteins help molecules move across the membrane, it it called Facilitated Diffusion
What requires the use of energy and help of transport proteins to move a molecule across a cell membrane?
Facilitated diffusion
How simple diffusion can be distinguished from facilitated diffusion?
simple diffusion transports smaller molecules like oxygen and water while facilitated diffusion transports larger molecules like glucose and requires energy
Does facilitated diffusion require ATP?
In cells, passive diffusion is energy independent and therefore does not require ATP. This is opposed to active transport which requires either energy in the form of ATP or a charge gradient to move a molecule or ion across the membrane.
What carrier proteins help in facilitated diffusion in the cell membrane?
Integral proteins.

Facilitated diffusion and active transport?
Facilitated diffusion = down concentration gradient, it just uses a carrier protein (doesn't need energy)Active transport =goes UP concentration gradient with the help of a carrier protein and ENERGY
What is the process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane bound carrier proteins called?
The process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane bound carrier proteins is called facilitated diffusion. Facilitated transport is passive and does not directly require chemical energy from ATP.
What does a cell use during facilitated diffusion to help get substances in or out of the cell?
carrier protein
Facilitated diffusion sentence?
Facilitated diffusion is a type of diffusion specifically for larger molecules, to help them cross a selectively permeable membrane with the help of integral proteins that act as carriers. Facilitated diffusion is a passive process, i.e. it does not need energy/ATP.
Is facilitated diffusion is an active transport?
The name itself indicates there difference. Diffusion occurs without any other active participant/free flow diffusion is called Transport diffusion. Diffusion occurs with help of other active participant is called Facilitate Diffusion
What is the process When proteins help molecules move across the membrane is called?
when proteins help molecules move across the membrane, it it called Facilitated Diffusion
What is the difference between facilitated diffusion with the help of a carrier molecule with the help of a transport protein?
Facilitated diffusion is a type of passive transport (does not require energy). It is called facilitated diffusion because it utilises the carrier protein to diffuse through it. Active transport requires energy to pump certain big molecules to cross over and this uses transport protein. Basically, the difference is just the usage of energy.
What requires the use of energy and help of transport proteins to move a molecule across a cell membrane?
Facilitated diffusion
What are the main characteristics of facilitated diffusion?
both require special carrier molecule to move substances across the membrane
How simple diffusion can be distinguished from facilitated diffusion?
simple diffusion transports smaller molecules like oxygen and water while facilitated diffusion transports larger molecules like glucose and requires energy
