Enzymes are catalytic proteins or RNA molecules that accelerate chemical reactions. Substrates are the molecules that are acted upon by enzymes and are converted into products through the binding of substrates to an enzyme’s active site. Figure 1 below shows a protein enzyme’s active site and four potential protein substrates. Table 1 indicates the different chemical properties at several locations in a hypothetical enzyme’s active site, and Table 2 indicates the different chemical properties at several locations in the potential substrates. Locations labeled “A” in the enzyme’s active site and on the substrate will attempt to interact, as will locations that are labeled “B” and “C. Based on Figure 1, explain whether the enzyme is more likely to bind with substrate 2 or substrate 4.
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.
