Glucose molecules pass through membrane-spanning proteins, specifically glucose transporters, via facilitated diffusion. These transporters provide a hydrophilic pathway that allows glucose to move down its concentration gradient without requiring energy. The specific binding sites on the transporter recognize glucose molecules, undergoing conformational changes to shuttle them across the membrane. This process ensures efficient uptake of glucose in cells, especially in tissues like muscle and fat.
What else can I help you with?
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.
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.
What structure allows molecules such as glucose to move through the process of facilitated diffusion?
Facilitated diffusion allows molecules like glucose to move across cell membranes through specific protein channels or transporters. These membrane proteins facilitate the passive movement of glucose down its concentration gradient without requiring energy. The structure of these proteins includes binding sites that specifically recognize and transport glucose, enabling its efficient passage through the lipid bilayer.
The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called?
The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called facilitated diffusion. In this process, carrier proteins aid in the movement of glucose across the membrane down its concentration gradient.
Which protein is responsible for transport of glucose across cell membrane?
A family of proteins called GLUT carry glucose molecules across the cell membrane.
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.
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.

This process is facilitated by protein channels that specifically recognize and transport glucose molecules.
What molcule can pass through a lipid bilayer by simple diffusion with no assistance from proteins?
Carbon.water molecules,glucose molecules can pass through lipid bilayer by simple diffusion
What statement explains why oxygen molecules easily diffuse across a cell membrane which glucose molecules do not?
Glucose is too big to pass throught.
Facilitated diffusion moves large molecules through?
Facilitated diffusion moves large molecules through cell membranes with the help of specific carrier proteins. These proteins create channels in the membrane that allow large molecules to pass through and reach the inside of the cell. The process does not require energy input, as it relies on the concentration gradient of the molecules to drive their movement.

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.
The absorption of what monosaccharide does not require energy?
The absorption of glucose does not require energy. Glucose absorption occurs through facilitated diffusion, where glucose molecules move across the intestinal membrane down their concentration gradient with the help of transport proteins, such as GLUT2.
How is glucose absorbed into the bloodstream?
Glucose is absorbed into the bloodstream through a process called facilitated diffusion in the small intestine. Specialized proteins called glucose transporters help move glucose molecules from the intestine into the bloodstream, where it can be used for energy by the body's cells.
Can proteins be converted to glucose in the body?
Yes, proteins can be converted to glucose in the body through a process called gluconeogenesis.
