The Effects of Varying pH on Enzyme Activity A lab was conducted to test different pH balances on an enzyme. Introduction: Enzymes are protein catalysts that speed up a chemical reaction without being consumed in the process. Enzymes are three-dimensional structures that consist of one or more polypeptide chains. The polypeptide chains form an active site (where a substrate will fit into). Enzyme molecules are folded into a very specific shape held together by the different forces of attraction

optimum pH at which it is most active. An increase or decrease in the pH of the solution will cause the enzyme to have a change in its three dimensional shape. If an enzyme is placed in an environment that is to basic or acidic the reaction will take longer to digest the starch because the enzyme shape has changed and the substrate will have a harder time connecting to the active

The Effect of Soil pH on the Living Conditions In Lumbricus terrestris Abstract The difference in soil pH weighs a heavy measure on the appearance of the earthworm Lumbricus terrestris in different areas of soil. A highly acidic or highly alkaline soil may be the underlying reason for the absence of this earthworm in certain areas where pH plays a large role. In this experiment‚ soil pH was altered with Miracida soil acidifier and Agricultural Limestonea soil correctional for acidic soil

OUTLINE OF DOMESTIC WASTEWATER TREATMENT IN VIETNAM 1 - Policy framework Regarding laws and regulations on waste processing and water treatment the Vietnamese government has issued decrees which contain the standards and requirements companies have to comply with. Although these standards are at a relatively high level‚ Vietnam still has to face environmental challenges due to infringement. The reasons for that are mostly not accomplishable claims‚ a lack of enforcement and a non-sufficient

activity of the enzyme catecholase in different pH levels as well as its absorbance in differently concentrated solutions. A spetrophotometer was used to measure the absorbance of the enzyme catecholase in different pH solutions as well as to measure the absorbance of catecholase in solutions with different concentrations of potato juice and phosphate buffers. Absorbance of the enzyme catecholase was at an optimum level when pH was close to neutral. When pH was acidic or basic‚ the catecholase was less

Determination of the Effect of pH on Amylase Activity Grace Chung Abstract: Amylase is an important enzyme in the human body as it allows for the consumption of starch by breaking the polysaccharide down into maltose units. All enzymes‚ including amylase‚ function best at a certain optimal pH. Therefore‚ in this experiment‚ the effect of different pHs on the reaction rate of amylase is studied. It was hypothesized that the amylase-starch reaction would proceed fastest at a pH closest to that of
