Cell membranes usually allow what substances to enter a cell?
the cell membrane allows what substance to enter the cells.
Where an enzyme and substance meet or connect?
Membrane Proteins, or transport site, these sites act as transporters, enzymes, cell surface receptors and cell surface identity markers, as well as aiding in cell-to-cell adhesion and securing the cytoskeleton.
What is it called when a part of a cell membrane closes around a molecule to allow the molecule to enter the cell?
This is called endocytosis.
How does lipid solubility affect the ability of substances entering a cell?
If the substance is not lipid soluble, it will not be able to pass through the cell membrane, which is a phospholipid bilayer. This means it will not be able to enter the cell.
Which type of receptors binds to ligands that cannot enter the cell?
Extracellular
