What does this phrase mean globular proteins that span the lipid bilayer?
I believe the 'lipid-bilayer' refers to the membrane of a cell. A globular protein is something that takes on a roughly spherical shape. In cells proteins span the outside of a cell to the inside to help with the diffusion of molecules or especially ions that do not diffuse directly through the membrane.
What types of molecules diffuse through the cell membranes by facilitated diffusion?
molecules that can survive the hydrophobic interior of the lipid bilayer
Can all molecules diffuse through all cell membranes?
No, there are specific cell membranes that allow only certain molecules to pass through. Some stay open and others must be opened ( like a gate ).
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable 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 particles can diffuse directly through the lipid bi-layer?
As the bilayer contains hydrophobic fatty acid tails, water-soluble molecules cannot diffuse directly through. However, lipid soluble molecules such as oxygen can diffuse directly through. Overall, for a molecule to be able to diffuse directly through it must be lipid-soluble, relatively small and non-polar.
Which substances readily diffuse through the membrane?
Small and non-polar molecules can readily pass through the cell membrane. They follow the concentration gradient, moving from the higher concentration area to the region of lower concentration.

How do you use diffuse in sentence?
Oxygen molecules diffuse across the membrane.
What type of molecule would be likely to diffuse across the phospholipid bilayer of the cell membrane?
an ion
Glucose is a molecule that can move across the cell membrane if the concentration of glucose is high or inside the cell than outside the cell then what will happen by the process of diffusion?
glucose molecules will diffuse out of the cell. apex

Do molecules diffuse during equilibrium?
No.
