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.
Does glucose enter or leave a cell?
Glucose enters a cell through facilitated diffusion using glucose transporters on the cell membrane. Once inside the cell, glucose is used in cellular respiration to produce energy.
How are glucose molecules moved Ino a cell?
The glucose goes in through the membrane and can in or out either ways.
How can you sterilize glucose by filtration?
Glucose cannot be sterilized by filtration because it is a small molecule that can easily pass through filters. Sterilization of glucose is typically achieved using methods like autoclaving or filtration through a sterile membrane with a pore size small enough to capture any microorganisms present in the solution.
What happens if a molecule is too large to go through a membrane?
The molecule will be transported across the membrane by way of a transport protein or protein channel.
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.
A molecule such as glucose must use a protein channel to cross through a cell membrane?
This is correct. Glucose, being a large molecule, requires a protein channel called a glucose transporter to facilitate its passage through the cell membrane. Glucose transporters assist in transporting glucose molecules across the hydrophobic lipid bilayer of the cell membrane.
What structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not?
A large glucose molecule requires facilitated diffusion but an oxygen molecule does not is a semipermeable 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.
What is A large glucose molecule requires facilitated diffusion but an oxygen molecule referring to?
A large glucose molecule requires facilitated diffusion because it is too big to pass through the cell membrane without assistance from transport proteins. In contrast, an oxygen molecule is small enough to diffuse freely across the cell membrane through simple diffusion due to its size and hydrophobic nature.
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.
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.
Which molecule among the following will not pass through the phospholipid bilayer of a membrane?
The molecule that will not pass through the phospholipid bilayer of a membrane is a large and polar molecule.
What will not diffuse through the cell membrane?
Glucose
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.
Which molecule would be unable to diffuse through a cell membrane?
A molecule that is too large or charged would be unable to diffuse through a cell membrane.
What does not freely diffuse through the plasma membrane?
glucose
