Glucose can move via two ways:
1. With the Sodium/glucose pump. As sodium is diffusing back into the cell the glucose will attach itself (co-transport) as a symporter across the membrane. The sodium is going with the gradient and the glucose is moving against its gradient. Therefore, Indirect active transport via a symporter as a co-transporter.
2. By facillitated diffusion by attaching itself to a proten carrier glucose will move with the gradient into the cell.
This means that glucose it the only molecule that can enter or leave a cell under two different transportation modes.

What is required to transport glucose molecules across the cell membranes of the intestine?
Glucose molecules are transported across the cell membranes of the intestine through facilitated diffusion using glucose transporters (GLUT proteins), particularly GLUT2 and GLUT5. These transporters help facilitate the movement of glucose into intestinal cells for absorption into the bloodstream.
How does the movement of materials across the cell membrane relate to an organisms survival?
If your cells can't get a steady stream of glucose, the cell will die.

What nutrients are absorbed by osmosis?
Nutrients such as water, minerals, and small molecules like glucose are absorbed by osmosis in the small intestine. Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.
Which protein is responsible for transport of glucose across cell membrane?
A family of proteins called GLUT carry glucose molecules across the cell membrane.
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 does a cell solve the problem of glucose being to big to pass through the cell membrane?
Cells use transport proteins, such as glucose transporters, to facilitate the movement of glucose molecules across the cell membrane. These transporters act as channels or carriers that allow glucose to pass through the membrane, overcoming the barrier posed by its size.
Why glucose molecules can easily pass across the semipermeable cell membrane?
Glucose molecules cannot easily pass through the semipermeable cell membrane due to their size and polarity; they are larger and polar, making them less able to diffuse freely through the lipid bilayer. Instead, glucose requires specific transport proteins, such as glucose transporters (GLUT), which facilitate its movement across the membrane via facilitated diffusion. This process allows glucose to enter cells efficiently without the expenditure of energy.
Why cant glucose be able to move across a cell membrane by simple diffusion?
Glucose is a large and polar molecule, which makes it difficult to pass through the hydrophobic interior of the cell membrane. As a result, glucose requires specific transporter proteins to facilitate its movement across the membrane.
