What is allosteric regulation activation?

Posted April 4, 2024


Answer

Allosteric activation and inhibition refer to two main types of allosteric regulation, which involves the regulation of enzyme activity through the binding of an effector molecule at sites other than the enzyme's active site. 

Allosteric Activation: Allosteric activation occurs when a molecule binds to an allosteric site on the enzyme and enhances its activity. The binding of the activator molecule induces a conformational change in the enzyme, increasing its affinity for the substrate. This results in an increase in enzyme activity and an increased rate of the catalyzed reaction.

Allosteric activation is an important regulatory mechanism in cells, allowing for the modulation of metabolic pathways and enzyme functions in response to changing cellular conditions.
