How do your cells get oxygen glucose and the raw materials that they need to respire?
Your cells get oxygen and glucose through protein channels located on their cell membrane the phospholipid bilayer surrounding a cell.
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.
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
Which of the following would likely move through the lipid bilayer of a plasma membrane most rapidly?
Water, or small hydrophobic compounds.
Why does glucose pass through the membrane faster then mannose and galactose?
There are glucose carriers in the plasma membrane

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.
What is the purpose of the proteins in the bilayer?
They can be used to carry things across the membrane. for example, glucose is too large to diffuse through, so a protein must be used to carry it.

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.
What will not diffuse through the cell membrane?
Glucose
Which molecules are often embedded within the lipid bilayer to help substances through move through the membrane?
proteins.proteins
Some materials can move across the cell membrane against a concentration gradient by?
Large molecules such as glucose that cannot cross the phospholipid bilayer can still move across the membrane through transport proteins by active transport. Active transport uses energy to move molecules the bilayer.
