Enzyme kinetics
In biochemistry, enzymes are proteins that act as biological catalysts. Catalysis is the addition of a catalyst to a chemical reaction to speed up the pace of the reaction. Catalysis can be categorized as either homogeneous or heterogeneous, depending on whether the catalysts are distributed in the same phase as that of the reactants. Enzymes are an essential part of the cell because, without them, many organic processes would slow down and thus will affect the processes that are important for cell survival and sustenance.
Regulation of Enzymes
A substance that acts as a catalyst to regulate the reaction rate in the living organism's metabolic pathways without itself getting altered is an enzyme. Most of the biological reactions and metabolic pathways in the living systems are carried out by enzymes. They are specific for their works and work in particular conditions. It maintains the best possible rate of reaction in the most stable state. The enzymes have distinct properties as they can proceed with the reaction in any direction, their particular binding sites, pH specificity, temperature specificity required in very few amounts.
Each enzyme has a characteristic pH value at which it catalyzes its reaction with the fastest rate and optimum capacity. This specific pH is termed it be its optimum pH . Optimum pH can be both acidic or alkaline for any enzyme depending on its type. Change in the pH level in the environment or medium of reaction leads to change in concentration of H+ ions. These ions alter the structure of the enzyme or substrate either by breaking the already existing bonds or creating new additional bonds with any of the two proteins available.
