The Central Role of Enzymes as Biological Catalysts - The ...
A fundamental task of proteins is to act as enzymes—catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins. In the absence of enzymatic catalysis, most biochemical reactions are so slow that they would not occur under the mild conditions of …

Effect of pH on Enzymatic Reaction - Creative Enzymes
Effect of pH on Enzymatic Reaction. The pH scale is used to measure the acidity or alkalinity of a sample and describes how many hydrogen ions or hydroxides are present in the sample. The change of pH will lead to the ionization of amino acids atoms and molecules, change the shape and structure of proteins, thus damaging the function of proteins.

Biological Catalysts - Enzymes | A-Level Biology Revision ...
Enzymes are highly specific for one reaction or a class of reactions, based on the structure of their active sites. Enzymes allow reactions to take place on their surface via specific binding of their substrate but do not take part in the reaction. Enzymes describe a class of proteins that are biological catalysts.
Enzyme-substrate Complex - Biology Wise
Enzyme-substrate Complex. In a chemical reaction, the step wherein a substrate binds to the active site of an enzyme is called an enzyme-substrate complex. The activity of an enzyme is influenced by certain aspects such as temperature, pH, co-factors, activators, and inhibitors.
