What else can I help you with?
What statement explains why oxygen molecules easily diffuse across a cell membrane which glucose molecules do not?
Glucose is too big to pass throught.
What type of transport is it when gluclose molecules move into a cell?
Glucose molecules entering a cell typically occurs through facilitated diffusion, which is a type of passive transport. This process involves the movement of glucose across the cell membrane with the help of specific transporter proteins.
How do glucose molecules cross a plasma membrane on the apical side of epithelial cells?
Glucose molecules cross the plasma membrane on the apical side of epithelial cells through facilitated diffusion using glucose transporters such as GLUT1 and GLUT2. These transporter proteins help the glucose molecules move down their concentration gradient into the 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.
Carrier proteins transport glucose into a muscle cell.?
carrier proteins transport glucose into a muscle cell
Why do cells need carriers proteins that transport glucose?
Large molecules, such as glucose, are not able to pass through the cell membrane. Therefore proteins are needed to transport them across.
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.
Why oxygen molecules do not across a cell membrane while glucose molecules do not?
Glucose is too big to pass throught.
There is a need for glucose inside a cell but the glucose molecule is too large to pass through the cell membrane How does the cell solve this problem?
The cell solves this problem by using transport proteins called glucose transporters. These transporters serve as gateways in the cell membrane, allowing glucose molecules to pass through into the cell. This process is facilitated by protein channels that specifically recognize and transport glucose molecules.
Which protein is responsible for transport of glucose across cell membrane?
A family of proteins called GLUT carry glucose molecules across the cell membrane.
When molecules pass through a cell membrane using special proteins called transport proteins?
When molecules pass through a cell membrane using special proteins called transport proteins, this process is known as facilitated diffusion or active transport, depending on whether energy is required. Transport proteins help move substances across the membrane by forming channels or carriers that allow specific molecules, such as glucose or ions, to enter or exit the cell. This mechanism ensures that essential nutrients are absorbed while waste products are expelled, maintaining cellular homeostasis.
What statement explains why oxygen molecules easily diffuse across a cell membrane which glucose molecules do not?
Glucose is too big to pass throught.
Mitochondria are needed for the cell to transport glucose across the cell membrane into the blood what is the method that the cell uses to do this?
Mitochondria are not directly involved in transporting glucose across the cell membrane. Glucose transport into the cell is primarily facilitated by glucose transport proteins located on the cell membrane. These transport proteins utilize concentration gradients to move glucose into or out of the cell as needed.

Glucose molecules entering a cell typically occurs through facilitated diffusion, which is a type of passive transport. This process involves the movement of glucose across the cell membrane with the help of specific transporter proteins.

Glucose molecules cross the plasma membrane on the apical side of epithelial cells through facilitated diffusion using glucose transporters such as GLUT1 and GLUT2. These transporter proteins help the glucose molecules move down their concentration gradient into the cell.
What substance not permeable at the cell membrane?
Large polar molecules like glucose and ions such as sodium and potassium are not permeable through the cell membrane. These molecules require specific transport proteins or channels to facilitate their movement across the membrane.
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.
