1. Enzymes do not function optimally at low temperatures. The optimal temperature of enzyme actuacti lies between 20 to 37 degree celsius. At this temperature, the product released with increasing time, increases steadily.
2. For graphing, the x-axis is divided into 60 seconds, and the y axis is divided into 90 units (02 ml). Each point is plotted on the graph according to the data table, and the respective graphs are drawn.
3. Enzymes are biological catalysts that speed up the rate of a reaction. Enzymes belong to proteins (macromolecule).
pH prediction: Enzymes do not function well at very high or very low pH. The optimal pH for enzyme activity remains around pH 7. At low pH, little product is produced by the enzyme. At high pH, a moderate amount of product is produced by the enzyme.

1 of 1 Part D-A typical enzyme experiment A common enzyme studied in many introductory biology labs is catalase, which is found in high concentration in most cells, promoting the decomposition of hydrogen peroxide (H2O2) Hydrogen peroxide is formed as a by-product of chemical reactions and would soon kill cells if not immediately removed or broken down into its products--water and oxygen-as shown by the following equation Catalase 2 H2O, → 2 H2O + 0, You may be familiar with...
how does changing saline concentration affect enzyme activity? (only saline not ph) what is the hypothesis Enzyme Activity Design Investigation The compound hydrogen peroxide, Hou by product of the reaction in most living organisms. However, Hydrogen peroxide is damaging to delicate molecules inside ces As a result, nearly all organisms produce the enzyme catalase, which breaks down H,O, it is formed Potatoes are one source of catalase Catalase speeds up the breakdown of hydrogen peroxide into water and gaseoul sxygen...
Does anyone know how to do this? Thanks in advance! Enzyme Activity (ml) Effect of pH on (amylase) enzyme activity. For determination of optimum assay pH of the enzyme reaction, 0.05 M Na2HPO4-NaH2PO4 buffer was used. The reaction was carried out for 10 min at 50°C in a shaking water. The enzyme activity was measured and the results are presented on graph, Bars represent means standard deviations for three replicates. 1. What do the error bars in this graph represent?...

This was a analysis questioned asked on my lab report ? I need help, I included part C on there and the whole procedure of how it works. Will you please help me how to determine the concentration in a concentration % ? Heres the question: 4. For the 10 mixtures that were created in Part C: Classification of Mixtures procedure, determine the concentration in a concentration % (m/m, v/v, or m/v). Include a unit with your value and a...

Foundations of Biological Sciences 1 Enzymes - 8 PART 4: THE EFFECT OF PH ON ENZYME ACTIVITY The pll scale measures the amount Another factor influencing the rate of enzyme catalysis is the pll of the of ons in a solution. The more solution. pH specifies the acidity or basicity of solution by measuring the the more acidic the solution and lower hydrogen ion consentation (H). Like temperature, pH affects the three- pH) dimensional shape of enzymes, thus regulating their...
Please help! (These are the instructions I had) 1) Preparation of K2[Cu(C2O4)2] 2H2O CuSO4•5H2O + 2K2C2O4•H2O → K2[Cu(C2O4)2]•2H2O + K2SO4 + 5H2O Heat a solution of 2.5g of potassium oxalate monohydrate in 12.5mL of water contained in a 50mL beaker (approx. 90°C). Heat 1.55g of copper sulfate pentahydrate in 3mL of water to about 90°C and add it rapidly, with vigorous stirring to the hot potassium oxalate solution. Set on the bench and allow to cool to room temperature then...
