Endocytosis:
Types of Endocytosis: Phagocytosis, Pinocytosis, Receptor-Mediated
By diffusing across the protein membrane.
Globular Proteins
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
If you mean through the cells itself, that would be the endoplasmic reticulum but if you mean substances from the outside of the cell into the cell that is done by protein channels.
Protein, because thats what the cell membrane does (delivers protein to the cell)
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.
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.
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.
There would be no protein synthesis.
