Why is it necessary for glucose to be pumped into the cell rather than diffusing in?
Glucose cannot pass through a phospholipid bilayer by simple diffusion.
How do Lipid-soluble molecules and gases enter the cell?
diffusion through the lipid bilayer.
Gases such as oxygen and carbon dioxide cross the plasma membrane by?
passive diffusion through the lipid bilayer
Why do oxygen molecules easily diffuse across a cell membrane while glucose molecules do not?
Oxygen molecules are small and nonpolar, which allows them to easily pass through the hydrophobic lipid bilayer of the cell membrane via simple diffusion. Glucose molecules, on the other hand, are larger and polar, making it more difficult for them to move through the nonpolar interior of the lipid bilayer. They require specific transport proteins or channels to facilitate their movement across the membrane.
The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called?
Facilitated diffusion is the process by which glucose can pass through a cell membrane by combining with special carrier molecules.
Is glucose permeable through phospholipid bilayer?
Glucose does not readily diffuse across a lipid bilayer. In order for glucose to travel into the cell, it needs the help of a transport protein. This is called a facilitated diffusion.
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
Why is it necessary for glucose to be pumped into the cell rather than diffusing in?
Glucose cannot pass through a phospholipid bilayer by simple diffusion.
Why do you think diffusion of ions through these channels is generally a slower process than diffusion through the lipid bilayer?
Nope. It Is diffusion
Why cant glucose be able to move across a cell membrane by simple diffusion?
the lipid bilayer forms a barrier to water soluble substances such as glucose
How do Lipid-soluble molecules and gases enter the cell?
diffusion through the lipid bilayer.
Gases such as oxygen and carbon dioxide cross the plasma membrane by?
passive diffusion through the lipid bilayer
A form of diffusion that going to past through the bloodstream?
Glucose

What are molecules on the cell membrane responsible for?
Letting different molecules in and out of a cell. Chemicals including steroid hormones, reactants and products of respiration...ect. the chemicals have to pass through the phospholipid bilayer (which is made from phosphates and fatty acid chains) molecules pass through the bilayer through passive diffusion, facilitated diffusion and active transport.
The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called?
Facilitated diffusion is the process by which glucose can pass through a cell membrane by combining with special carrier molecules.
Which substances may pass through a cell membrane by simple diffusion?
Small, uncharged molecules can pass through the phospholipid bilayer, notably oxygen and carbondioxide.Other substances may pass through channel and carrier proteins by diffusion, sometimes referred to as facilitated diffusion as the proteins facilitate (make possible) the passage of substances that cannot cross the lipid layer. These substances include glucose and a variety of ions that are moving down their concentration gradients.
