What statement explains why oxygen molecules easily diffuse across a cell membrane which glucose molecules do not?
Glucose is too big to pass throught.
Why does glucose pass through the membrane faster then mannose and galactose?
Glucose passes through the membrane faster than mannose and galactose because glucose is the primary energy source for many cells and is recognized and transported more efficiently by glucose transporters present on the cell membrane. Mannose and galactose have different transporter proteins with lower affinity and therefore pass through the membrane at a slower rate.
Why is glucose allowed to pass through a semipermeable membrane and not starch?
Whether molecules are able to pass through the membrane depends on the size of the molecules. Smaller ones can, and larger ones cannot. Glucose can pass through a cell membrane because it is a monomer, which is a smaller molecule than the polymer molecules of starch.
Can charged molecules pass through the membrane?
Yes, charged molecules can pass through the membrane.
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.
How do glucose pass through the membrane pores?
by moving.

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.
What membrane of the red cell will allow water oxygen carbon dioxide and glucose to pass through?
Plasma membrane

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?
It transports the glucose through transport proteins.
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.
What explains why oxygen molecules diffuse across a cell membrane while glucose molecules do not?
Glucose is too big to pass through.
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 allows glucose molecules to pass through membrane-spanning proteins?
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.
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.
