  2. Substrate (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Substrate_(chemistry)

    In this reaction, the substrate is a milk protein (e.g., casein) and the enzyme is rennin. The products are two polypeptides that have been formed by the cleavage of the larger peptide substrate. Another example is the chemical decomposition of hydrogen peroxide carried out by the enzyme catalase.

  3. Substrate (biology) - Wikipedia

    en.wikipedia.org/wiki/Substrate_(biology)

    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.

  4. Substrate - Wikipedia

    en.wikipedia.org/wiki/Substrate

    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

  5. Active site - Wikipedia

    en.wikipedia.org/wiki/Active_site

    Organisation of enzyme structure and lysozyme example. Binding sites in blue, catalytic site in red and peptidoglycan substrate in black. (In biology and biochemistry, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction.

  6. Substrate presentation - Wikipedia

    en.wikipedia.org/wiki/Substrate_presentation

    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.

  7. Substrate (aquatic environment) - Wikipedia

    en.wikipedia.org/wiki/Substrate_(aquatic...

    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.

  8. Lithotroph - Wikipedia

    en.wikipedia.org/wiki/Lithotroph

    The energy obtained from inorganic oxidation varies depending on the substrate and the reaction. For example, the oxidation of hydrogen sulfide to elemental sulfur by ½O 2 produces far less energy (50 kcal/mol or 210 kJ/mol) than the oxidation of elemental sulfur to sulfate (150 kcal/mol or 627 kJ/mol) by 3/2 O 2,. [10]

  9. Enzyme catalysis - Wikipedia

    en.wikipedia.org/wiki/Enzyme_catalysis

    Substrate, bound substrate, and transition state conformations of lysozyme. The substrate, on binding, is distorted from the half chair conformation of the hexose ring (because of the steric hindrance with amino acids of the protein forcing the equatorial c6 to be in the axial position) into the chair conformation, [ 29 ] which is similar in ...
