Cell membrane consist of phosholipid layres and have small pores in it aproximately of the size of 80nm which allows only those molecules which are smalles then this pore size. So it is semi or selective permeable.
Glycogen has a had time passing through a cell membrane in comparison to water.
It acts as a facilitator to allow water-soluble subtances to pass through the cell membrane
Some molecules can't go through the cell membrane.
PROTEIN!!!!!!!!!!!!!!!!!!!!!!!!!
No, phenolphthalein cannot pass through a cell membrane on its own. It requires a carrier protein or a specific transport mechanism to facilitate its entry into a cell.
Glycogen has a had time passing through a cell membrane in comparison to water.
protein binds to a particle and uses energy to move through the cell membrane
Globular Proteins
Protein, because thats what the cell membrane does (delivers protein to the cell)
By diffusing across the protein membrane.
Channel proteins are a type of protein found in the cell membrane that regulate the passage of specific ions or molecules into or out of the cell. These proteins form channels or pores that allow substances to pass through the membrane, controlling the movement of substances across the cell membrane.

Cell membrane pores are made up of protein.
A membrane protein is a type of protein that is embedded within the cell membrane. It functions by helping to transport molecules in and out of the cell, acting as receptors for signaling molecules, and providing structural support to the cell membrane.
