What else can I help you with?
What can across the membrane with assistance?
Large or polar molecules, such as glucose or ions, typically require assistance to cross the cell membrane. This assistance can come in the form of transport proteins like channel proteins or carrier proteins that facilitate the movement of these molecules across the membrane.
How are glucose molecules moved Ino a cell?
The glucose goes in through the membrane and can in or out either ways.
What are carrier proteins?
Carrier proteins are proteins that bind to specific molecules and transport them across cell membranes. They are essential for facilitating the movement of molecules like ions, nutrients, and signaling molecules in and out of cells. Carrier proteins exhibit selectivity and saturation kinetics in their binding and transport activities.
What causes facilitated diffusion of glucose to occur faster from one solution to another?
Facilitated diffusion of glucose occurs faster due to the presence of specific carrier proteins that assist in the transport of glucose molecules across the membrane. These carrier proteins create channels or tunnels that increase the rate of glucose transport, enabling more efficient movement of glucose from one solution to another. Additionally, factors such as the concentration gradient and the number of carrier proteins present can also influence the speed of facilitated diffusion.
Which protein is responsible for transport of glucose across cell membrane?
A family of proteins called GLUT carry glucose molecules across the cell membrane.
Glucose and no other sugar is transported into cells by protein carrier molecules in the cell surface membrane. How do carrier molecules specifically recognize glucose?
Carrier molecules have specific binding sites that are complementary to the structure of glucose molecules. This allows the carrier molecules to selectively recognize and transport glucose across the cell membrane while excluding other sugars. The specificity of recognition is determined by the shape, size, and chemical properties of both the carrier molecule and the glucose molecule.
How would you describe the process of facilitated diffusion of glucose through carrier proteins?
Facilitated diffusion of glucose through carrier proteins is a passive process where glucose molecules move across the cell membrane with the help of specific carrier proteins. These carrier proteins bind to glucose molecules on one side of the membrane and release them on the other side, allowing glucose to move from an area of high concentration to an area of low concentration without requiring energy input from the cell.
Carrier proteins transport glucose into a muscle cell.?
carrier proteins transport glucose into a muscle cell
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 can across the membrane with assistance?
Large or polar molecules, such as glucose or ions, typically require assistance to cross the cell membrane. This assistance can come in the form of transport proteins like channel proteins or carrier proteins that facilitate the movement of these molecules across the membrane.
What is it called when transport proteins to help large molecules like glucose across the cell membrane?
Facilitated diffusion is the process by which transport proteins help large molecules like glucose cross the cell membrane. These proteins create a channel or carrier mechanism that allows the molecule to move across the membrane along its concentration gradient.
How do carrier protiens transport substances across cell membrane?
Carrier proteins facilitate the transport of substances across the cell membrane by binding to the specific molecules they transport and undergoing conformational changes to move the molecules across the membrane. This process is often referred to as facilitated diffusion. It allows for the transport of specific molecules, such as glucose or ions, across the membrane, down their concentration gradient.
What is a sentence with the word permease in it?
The carrier protein for the facilitated transport of glucose is called a permease.
Why do molecules easily diffuse across a cell membrane while glucose molecules do not?
Glucose is too big to pass throught.
How do glucose molecules cross a plasma membrane?
Facilitated Diffusion
Why oxygen molecules do not across a cell membrane while glucose molecules do not?
Glucose is too big to pass throught.
What explains why oxygen molecules diffuse across a cell membrane while glucose molecules do not?
Glucose is too big to pass through.
