Substrate theory
WebA substratum (plural: substrata) or substrate is a language that an intrusive language influences, which may or may not ultimately change it to become a new language. The term is also used of substrate interference; i.e. the influence the substratum language exerts on the replacing language.

Web18 Jan 2024 · The Receptor Theory: This theory suggests that drugs only work when they bind to specific receptors, producing a drug-receptor complex. This complex then triggers a cascade of events inside the cell, resulting in the drug’s desired effect.

WebEnzymes are high-molecular weight proteins that act on a substrate, or reactant molecule, to form one or more products. In 1913, Leonor Michaelis and Maude Menten proposed the following reaction mechanism for enzymatic reactions: E+ S k1 ⇌ k − 1ES k2 → E + P. where E is the enzyme, ES is the enzyme-substrate complex, and P is the product. WebThe success of transition metal-catalysed ortho-directed C–H activation is often plagued by the effects of undesirable interactions between the directing group (DG) and other groups introduced into the aromatic core of the substrate.In particular, when these groups are in neighbouring positions, their interactions can affect profoundly the efficacy of the C–H …
