Question

construct a model that describes how an enzyme functions. Must use; activation energy, active site, allosteric regulation, coenzymes, cofactors, competitive inhibition, environmental optimization, enzyme, induced fit, product, protein, regulatory site, substrate, transition state

Answer 1

Enzymes are bio catalysts that is protein in nature and function to reduce the activation energy of the substrates and thus facilitates the formation of products. Enzymes are made up of a protein part and a non protein part. The non protein part is either a cofactor or inorganic molecule/ions or a organic group called Coenzyme. Substrates bind to the active site of the enzyme to produce the transition state much faster to produce the products.This binding of the substrate to the enzyme occurs via the induced fit model where the active site changes the conformation of the active site to properly fit the substrate. Enzyme contains other regulatory sites other than the active called the allosteric site where activators or inhibitors can bind to it to either facilitate or hinder the reaction. This phenomenon is called allosteric regulation. When a inhibitor is present in the recation that binds the active site and prevents the substrate from binding is called competitive inhibition because this molecule competes for the binding site. Environmental optimisation results in the Enzyme function to be enhanced according to its specific conditions of its environment and its function.
