Cells can regulate the diffusion of molecules through protein channels by controlling the opening and closing of these channels. This regulation can be achieved through various mechanisms, such as changes in the cell's membrane potential or the binding of specific molecules to the channel proteins. By adjusting the activity of these channels, cells can selectively allow certain molecules to pass through while blocking others.
What else can I help you with?
How does number of protein channels affect diffusion in a cell.?
The number of protein channels in a cell directly affects the rate of diffusion of molecules across the cell membrane. A higher number of protein channels allow for more molecules to pass through, leading to faster diffusion. Conversely, a lower number of protein channels may result in slower diffusion rates.
Diffusion with a channel protein?
Channel proteins facilitate the passive movement of molecules down their concentration gradient. They form channels across the cell membrane, allowing specific molecules to move in and out of the cell without requiring energy input. This process is known as facilitated diffusion.
What are diffusions of particles through protein channels called?
Diffusion of particles through protein channels is called facilitated diffusion. This process allows specific molecules or ions to pass through the cell membrane with the help of transport proteins.
What is channel-mediated diffusion a subtype of?
Diffusion carried out by protein channel is termed channel mediated diffusionRead more http://www.kgbanswers.com/what-is-channel-mediated-diffusion/4450816#ixzz1EANNtr00
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.

The number of protein channels in a cell directly affects the rate of diffusion of molecules across the cell membrane. A higher number of protein channels allow for more molecules to pass through, leading to faster diffusion. Conversely, a lower number of protein channels may result in slower diffusion rates.
What is the difference between diffusion and facilitate diffusion?
The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.
What is the role of protein channelsin the cell membrane?
Protein channels allow the cell membrane to transfer large molecules across it. Remember, diffusion only occurs with small molecules. Protein channels are a necessity to transfer larger molecules.
Diffusion with a channel protein?
Channel proteins facilitate the passive movement of molecules down their concentration gradient. They form channels across the cell membrane, allowing specific molecules to move in and out of the cell without requiring energy input. This process is known as facilitated diffusion.
What is unique about the protein channels which are used by molecules that travel by facilitated diffusion?
Protein channels used in facilitated diffusion are unique because they are highly selective, allowing only specific molecules or ions to pass through based on size, charge, or chemical properties. These channels can be gated, opening or closing in response to specific stimuli, which helps regulate the flow of substances across the membrane. Additionally, they facilitate the movement of molecules down their concentration gradient without requiring energy, making the process efficient and vital for cellular function.

How are proteins used in biological membranes?
there are protein channels in the membranes and it regulate the entry of the molecules of different size.

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.
In what type of passive transport do protein channels assist molecules across the membrane?
In facilitated diffusion, protein channels assist molecules in crossing the cell membrane. This type of passive transport allows substances, such as ions and polar molecules, to move down their concentration gradient without using energy. The protein channels provide a pathway through the lipid bilayer, enabling the selective transport of specific molecules.
Is facilitated diffusion?
Facilitated Diffusion is the movement of molecules across cell membranes through protein channels and carrier proteins.Facilitated diffusion is a passive transport process, aka no energy required, where substances move down their concentration gradient (high concentration to low concentration) across a protein through a membrane protein because it is unable to diffuse directly through the phospholipid portion of the membrane itself.Diffusion of molecules assisted by protein channels that pierce a cell membrane
How do you transport proteins in a cell make it easier for certain molecules to diffuse across a membrane?
Proteins in the cell membrane can act as transporters or channels, aiding in the facilitated diffusion of specific molecules across the membrane. These proteins provide a passageway for the molecules to move across the membrane by utilizing their specific structure and function. This process helps regulate the movement of molecules in and out of the cell.
