The induced-fit theory aims to explain how the interactions between an enzyme and a sub- strate facilitate the catalysis of chemical reactions. Which of the following properties of enzyme-substrate interaction best explains enzymatic catalysis according to the induced-fit model? A Environmental conditions can alter the affinity between a substrate and an enzyme by changing the conformation of the enzyme. B C D Conformation changes in both the enzyme and the substrate due to their chemical in- teractions lower the activation energy of the catalyzed reactions. The interactions between an enzyme and a substrate depend on both structural and chemical compatibility and are therefore highly specific. Enzymes remain chemically unaltered between cycles of enzymatic catalysis while sub- strates are transformed into products.
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.
