Why do you think movement of ions through ion channels is generally a slower process that diffusion?
Let's take something obvious. Where would a crowd of persons move faster? Where there is absolutely nothing to prevent their passage or where there is an open gate?
The same thing applies to the movement of ions. Movement of ions through ion channels is a slower process because (with a more scientific approach!) their movement is determined by the number of these ion channels whereas for diffusion, there is absolutely nothing to prevent the passage of the molecules.
What else can I help you with?
Is simple diffusion saturable?
No, simple diffusion is not saturable because it does not involve specific carrier proteins or channels that can become saturated as concentration increases. Instead, it is a passive process that relies on the concentration gradient of molecules for movement across a membrane.
What is the term for the movement of molecules from an area of lower concentration to an area of higher concentration?
If it is the movement of molecules then it is diffusion. If it the movement of water then it is osmosis
A form of passive transport that involves membrane proteins to aid in the movement of substances?
Facilitated diffusion is a form of passive transport that involves membrane proteins to aid in the movement of substances across a cell membrane. The membrane proteins act as channels or carriers to facilitate the passage of specific molecules that cannot freely diffuse across the lipid bilayer. This process does not require energy input from the cell.
What is the movement of molecules from greater to lower?
This movement is called diffusion, where molecules move from an area of higher concentration to an area of lower concentration in order to achieve equilibrium. The process is driven by the random motion of molecules and does not require energy input.
Water soluble molecules often enter or exit a cell in what process?
Water soluble molecules often enter or exit a cell through a process called facilitated diffusion. This process involves the movement of molecules across the cell membrane with the help of specific protein channels or carriers.
Why do you think diffusion of ions through these channels is generally a slower process than diffusion through the lipid bilayer?
Nope. It Is diffusion
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 term defines the movement of materials along concentration gradient through channels?
Facilitated diffusion defines he movement of materials along a concentration gradient through protein channels.
Is simple diffusion saturable?
No, simple diffusion is not saturable because it does not involve specific carrier proteins or channels that can become saturated as concentration increases. Instead, it is a passive process that relies on the concentration gradient of molecules for movement across a membrane.
How do ligand-gated channels facilitate the process of facilitated diffusion?
Ligand-gated channels are proteins that open in response to specific molecules, called ligands, binding to them. When these channels open, they allow certain ions or molecules to pass through the cell membrane, facilitating the process of facilitated diffusion. This means that the movement of these ions or molecules across the membrane is made easier and faster, helping maintain the balance of substances inside and outside the cell.
Diffusion is the process of movement of molecules under a concentration gradient?
Yes
What is an example of diffusion through ion channels?
An example of diffusion through ion channels is the movement of sodium ions (Na+) through sodium channels in neurons. These ion channels are selective for sodium ions and allow them to move down their concentration gradient across the cell membrane. This process is important for generating electrical signals in neurons.
Which process accomplishes the movement of gases illustrated by the arrows in th diagram?
The process that accomplishes the movement of gases illustrated by the arrows in the diagram is diffusion. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, resulting in the equal distribution of molecules. In this case, gases are moving down their concentration gradient through the process of diffusion.
Diffusion is defined as a movement of molecules?
Diffusion is the movement of molecules from an area of high concentration to an area of low concentration, driven by random thermal motion. This process results in the equal distribution of molecules in a given space over time.
What is the term for the movement of molecules from an area of lower concentration to an area of higher concentration?
If it is the movement of molecules then it is diffusion. If it the movement of water then it is osmosis
Is Diffusion made of small or large molecules?
Diffusion is not a substance. It is a physical process. Diffusion is the process where there is a movement of molecules from where they are abundant to where they are scarce. A more technical definition would be: Diffusion is a process in which molecules move from a region of higher concentration to a region of lower concentration.
What is the process of spreading out to fill a sapce uniformly?
The process of spreading out to fill a space uniformly is called diffusion. Diffusion occurs when particles move from an area of high concentration to an area of low concentration until they are evenly distributed. This process is driven by the random movement of particles.
