WebAt high temperatures, the rate of enzyme action decreases because the increased heat increases the concentration of the enzyme alters the active site of the enzyme changes the pH of the system neutralizes the acids and bases in the system. ... Enzymes Coined by Kuhne in 1878. Popularly known as biological catalysts. 1) CO 2 + H 2 O ← Carbonic anhydrase H 2 CO 3 {\displaystyle {\ce {CO2{}+H2O<-[{\text{Carbonic anhydrase}}]H2CO3}}} (in lungs ; low CO 2 concentration) (2) The rate of a reaction is dependent on the activation energy needed to form the transition state which then decays into products. Enzymes increase reaction … See more Enzymes are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as See more Enzymes are generally globular proteins, acting alone or in larger complexes. The sequence of the amino acids specifies the structure which in turn determines the catalytic activity of the enzyme. Although structure determines function, a novel enzymatic activity … See more Some enzymes do not need additional components to show full activity. Others require non-protein molecules called cofactors to be bound for activity. Cofactors can be either inorganic (e.g., metal ions and iron–sulfur clusters) or organic compounds See more By the late 17th and early 18th centuries, the digestion of meat by stomach secretions and the conversion of starch to sugars by plant extracts and saliva were known but the … See more Enzymes can be classified by two main criteria: either amino acid sequence similarity (and thus evolutionary relationship) or … See more Substrate binding Enzymes must bind their substrates before they can catalyse any chemical reaction. Enzymes are usually very specific as to what See more As with all catalysts, enzymes do not alter the position of the chemical equilibrium of the reaction. In the presence of an enzyme, the reaction runs in the same direction as it would … See more
