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.
Two experiments were performed with the enzyme
ribonuclease. In experiment 1 the effect of increasing
substrate concentration on reaction velocity was measured.
In experiment 2 the reaction mixtures were identical to
those in experiment 1 except that 0.1 mg of an unknown
compound was added to each tube. Plot the data according
to the Lineweaver-Burk method. Determine the effect of the
unknown compound on the enzyme’s activity. (Substrate
concentration is measured in millimoles per liter. Velocity is
measured in the change in optical density per hour.)
