Substrate (aquarium), the material used in the bottom of an aquarium; Substrate (building), natural stone, masonry surface, ceramic and porcelain tiles; Substrate (chemistry), the reactant which is consumed during a catalytic or enzymatic reaction; Substrate (materials science), the material on which a process is conducted
In the former sense, a reagent is added to the substrate to generate a product through a chemical reaction. The term is used in a similar sense in synthetic and organic chemistry, where the substrate is the chemical of interest that is being modified. In biochemistry, an enzyme substrate is the material upon which an enzyme acts.
In biology, a substrate is the surface on which an organism (such as a plant, fungus, or animal) lives.A substrate can include biotic or abiotic materials and animals. For example, encrusting algae that lives on a rock (its substrate) can be itself a substrate for an animal that lives on top of the algae.
Substrate is a term used in materials science and engineering to describe the base material on which processing is conducted. Surfaces have different uses, including producing new film or layers of material and being a base to which another substance is bonded.
Substrate is the earthy material that forms or collects at the bottom of an aquatic habitat. It is made of sediments that may consist of: Silt – A loose, granular material with mineral particles 0.5 mm or less in diameter.
The substrate of an aquarium refers to the material used on the tank bottom. It can affect water chemistry, filtration, and the well-being of the aquarium's inhabitants and is also an important part of the aquarium's aesthetic appeal.
The active site consists of amino acid residues that form temporary bonds with the substrate, the binding site, and residues that catalyse a reaction of that substrate, the catalytic site. Although the active site occupies only ~10–20% of the volume of an enzyme, [ 1 ] : 19 it is the most important part as it directly catalyzes the chemical ...
Substrate presentation; A substrate (purple rectangle) is shown sequestered into a lipid domain (green lipids). The substrate's translocation to the disordered region (grey lipids) presents it to its enzyme (blue oval) where it is hydrolyzed. In molecular biology, substrate presentation is a biological process that activates a protein.
