No, simple diffusion does not require a helper protein. It is the passive movement of molecules across a cell membrane from an area of higher concentration to an area of lower concentration, relying on the concentration gradient. This process occurs directly through the lipid bilayer of the membrane for small, nonpolar molecules like oxygen and carbon dioxide.
What else can I help you with?
Does simple diffusion require the use of channels?
No, simple diffusion does not require the use of channels. It is the process by which molecules move across a membrane directly through the lipid bilayer, driven by concentration gradients. This means that small, nonpolar molecules like oxygen and carbon dioxide can freely pass through the membrane without the need for protein channels. However, for larger or polar molecules, facilitated diffusion using channels or carriers is necessary.
What action does not require the cell to use ATP?
Diffusion does not require the use of any ATP.
What is the basic difference between simple diffusion and facilitated diffusion across a cell membrane?
The basic difference between simple diffusion and facilitated diffusion lies in the mechanism of transport. Simple diffusion involves the movement of small, nonpolar molecules directly across the lipid bilayer of the cell membrane without the need for protein assistance, driven by a concentration gradient. In contrast, facilitated diffusion requires specific transport proteins, such as channels or carriers, to help larger or polar molecules cross the membrane, also following a concentration gradient. Both processes are passive and do not require energy.
What are the two types of possive transport?
The two types of passive transport are simple diffusion and facilitated diffusion. Simple diffusion involves the movement of molecules across a cell membrane without the need for a specific protein. Facilitated diffusion, on the other hand, requires the assistance of specific transport proteins to move molecules across the membrane.
Two types of passive transports are?
PASSIVE TRANSPORTS ARE OF TWO TYPES. 1)SIMPLE DIFFUSION 2)FACILITATED DIFFUSION 1)SIMPLE DIFFUSION:-diffusion of water and dissolved gas is simple. when concentration on both sides of membrane becomes the same,it stops. 2)FACILITATED DIFFUSION:-this also occurs along concentration gradient with help of carrier molecules.
What is the similarity between simple diffusion and facilitated diffusion?
both need transport protein
This is the process whereby a protein assists in simple diffusion?
Active transport
How does faciliated diffusion differ from simple diffusion?
Facilitated diffusion needs some sort of help. Often it would be a protein. Simple diffusion doesn't. If you spill something smelly on the floor in the kitchen, you will smell it all through the house. It will spread by simple diffusion.
What are the three transport processes that do not require cell energy?
Passive Transport,Facilitated Diffusion, and Simple Diffusion
Why does NaCl not require a transport protein for diffusion?
NaCl can diffuse freely across cell membranes through ion channels or transporters that allow for passive movement down its concentration gradient. As a small and simple molecule, NaCl does not require a specific transport protein for diffusion like larger or more complex molecules.
Does simple diffusion require the use of channels?
No, simple diffusion does not require the use of channels. It is the process by which molecules move across a membrane directly through the lipid bilayer, driven by concentration gradients. This means that small, nonpolar molecules like oxygen and carbon dioxide can freely pass through the membrane without the need for protein channels. However, for larger or polar molecules, facilitated diffusion using channels or carriers is necessary.
Does simple diffusion require ATP?
No only active transport requires ATP.
What are the 2 types of diffusion and explain fully?
The two types of diffusion are passive diffusion and facilitated diffusion. Passive diffusion is the movement of molecules across a membrane without the need for a protein carrier, driven by the concentration gradient. Facilitated diffusion involves the use of specific protein channels or carriers to help molecules move across the membrane, still following the concentration gradient without requiring energy.
What action does not require the cell to use ATP?
Diffusion does not require the use of any ATP.
How is faciliated transport similar to simple diffusion?
Facilitated and simple diffusion both transport solutes along a concentration gradient and neither processes require any ATP expenditure.
How is active transport different than simple and facilitated diffusion?
simple and facilitated diffusion don't require energy and are forms of passive transport. Active transport requires energy
