You are studying the enzyme Homerase and you notice that the rate of product formation increases as you add more substrate to a constant number of enzymes. However past a certain concentration of added substrate molecules, the rate no longer increases even though you keep increasing the substrate concentration. Which of the following statements likely accounts for this observation? a. This is an example of feedback inhibition b. Since the free energy for the reaction doesn't change in the presence of an enzyme, it can only reach a certain energy level maximum c. The product molecules must be acting as competitive inhibitors d. All the enzymes are complexed with substrate molecules
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.
