Enzyme induction is a process in which a molecule (e.g. a drug) induces (i.e. initiates or enhances) the expression of an enzyme.. Enzyme inhibition can refer to . the inhibition of the expression of the enzyme by another molecule
Stereoisomers of Soman, a G-series nerve agent and suicide inhibitor of acetylcholinesterase.Note the non-carbon chiral center.. In biochemistry, suicide inhibition, also known as suicide inactivation or mechanism-based inhibition, is an irreversible form of enzyme inhibition that occurs when an enzyme binds a substrate analog and forms an irreversible complex with it through a covalent bond ...
An inhibitor can reduce the effectiveness of a catalyst in a catalysed reaction (either a non-biological catalyst or an enzyme).E.g., if a compound is so similar to (one of) the reactants that it can bind to the active site of a catalyst but does not undergo a catalytic reaction then that catalyst molecule cannot perform its job because the active site is occupied.
Cells utilize product inhibition to regulate of metabolism as a form of negative feedback controlling metabolic pathways. [2] Product inhibition is also an important topic in biotechnology, as overcoming this effect can increase the yield of a product, such as an antibiotic. [3] Product inhibition can be competitive, non-competitive or ...
This inhibition may follow the competitive, uncompetitive or mixed patterns. In substrate inhibition there is a progressive decrease in activity at high substrate concentrations, potentially from an enzyme having two competing substrate-binding sites. At low substrate, the high-affinity site is occupied and normal kinetics are followed.
Competitive inhibition can be overcome by adding more substrate to the reaction, which increases the chances of the enzyme and substrate binding. As a result, competitive inhibition alters only the K m, leaving the V max the same. [3] This can be demonstrated using enzyme kinetics plots such as the Michaelis–Menten or the Lineweaver-Burk plot.
Releasing hormones and inhibiting hormones are hormones whose main purpose is to control the release of other hormones, either by stimulating or inhibiting their release. . They are also called liberins (/ ˈ l ɪ b ə r ɪ n z /) and statins (/ ˈ s t æ t ɪ n z /) (respectively), or releasing factors and inhibiting fac
Cognitive inhibition, the mind's ability to tune out irrelevant stimuli Inhibitory control, a cognitive process that permits an individual to inhibit their impulses; Inhibition of return, a feature of attention; Latent inhibition, a term used in classical conditioning; Memory inhibition, processes that suppress or interfere with specific memories
