Is enzyme a type of catalyst
WebJan 25, 2024 · Enzymes may be defined as an essential class of globular proteins that act as biocatalysts in the living systems and are produced by the living cells. Chemically all enzymes are globular proteins. However, some enzymes are associated with some non-protein components called the prosthetic group. WebCharacteristics of enzyme catalysis: A single molecule of the enzyme catalyst can transform up to a million molecules of the reactant per second. Hence, enzyme catalysts are said to be highly efficient. These biochemical catalysts are unique to certain types of reactions, i.e. the same catalyst cannot be used in more than one reaction. The ...
