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.
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.
Phosphorylation of sugars is often the first stage in their catabolism.Phosphorylation allows cells to accumulate sugars because the phosphate group prevents the molecules from diffusing back across their transporter.
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
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Gross anatomy is the study of structures large enough to be seen with the naked eye, and also includes superficial anatomy or surface anatomy, the study by sight of the external body features. Microscopic anatomy is the study of structures on a microscopic scale, along with histology (the study of tissues), and embryology (the study of an ...
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 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.
