You design an experiment to explore the effects of enzyme concentration on the rate of glucose (product) production. In the experiment, you prepare 5 tubes with equal amounts of water and substrate but altered the amount of enzyme. Tube #1 did not have enzyme, Tube #2 had 100 mg of enzyme, Tube #3 had 200 mg of enzyme, Tube #4 had 300 mg of enzyme, Tube #5 had 400 mg of enzyme. The results are summarized in the graph. Select all that apply. Given enough time all tubes (#1-5) would reach 1100 mg/dL. The substrate in tube #1 was denatured at 40 minutes. The fastest rate of reaction was in Tube #4. Adding more enzyme to Tube #5 at 40 minutes would produce more product. Tube #4 and #5 have run out of substrate at 40 minutes.
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.
