What are allosteric enzymes? Distinguish between MWC and KNF model

Allosteric enzymes are a type of enzyme that undergoes conformational changes when specific molecules, known as effectors or modulators, bind to sites other than the active site, called allosteric sites. These enzymes play a crucial role in regulating various biochemical pathways by altering their activity in response to changes in the environment or the presence of regulatory molecules. Allosteric regulation can either enhance or inhibit the enzyme’s activity, depending on whether the effector is an activator or an inhibitor.

In allosteric enzymes, the binding of an effector molecule can cause a structural change in the enzyme, which can either increase or decrease the enzyme's affinity for its substrate. This mechanism allows for fine-tuning of enzymatic activity in response to cellular needs, ensuring that biochemical processes proceed efficiently and accurately.
