A substrate is a substance or layer that is beneath something else. A substrate can be a surface or material that organisms live, grow, or get nourishment from. In biochemistry a substrate isa substance that is acted on by enzymes.

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.

Saturation Kinetics- an enzyme reaction in which there is enough enzymes to constantly have a substrate bound them and therefore the reaction is occurring at Vmax. This velocity is only limited by the concentration of substrates, not the enzyme.
