What is the difference between a substrate and a substratum?
They come from the same Latin word and often mean the same thing. "Substrate" is the standard term in science and manufacturing; "substratum" is more common in geology, linguistics and general figurative use, as in an underlying layer of meaning.
What is a substrate in biology?
Two things, depending on context. In biochemistry it is the specific molecule an enzyme binds and changes. In ecology and microbiology it is the surface or nutrient material an organism lives on or feeds from, such as agar in a culture dish.
What is the difference between a substrate and a reactant?
Every substrate is a reactant, but the word substrate specifically names the reactant that an enzyme or catalyst acts on. Chemists say "reactant" generally and "substrate" when a catalyst is doing the work.
