Factors that Affect the Rate of Reaction of Peroxidase Purpose: To determine the effect of various factors on the rate of reaction between an enzyme and its substrate‚ and also to determine the optimal ranges under which the enzyme activity is maximized. Also to determine whether saline and alcohol are inhibitors or activators Hypothesis: PH factor prediction: I predict that as the pH increases so the activity of the enzyme will increase until it reaches optimum pH range (pH 7) because the

Affect Rates Of Reaction Aim: How does the mass of calcium carbonate affect its rate of reaction with hydrochloric acid? Hypothesis: I hypothesize that when the mass of the calcium carbonate increases‚ the rate of reaction of the calcium carbonate and hydrochloric will also increase. The collision theory states that the more successful collisions there are within the reaction‚ the faster the rate of reaction. When the mass increases‚ so does the number of particles in the reaction‚ thus

Lab Report Factors That Affect Enzymes Reaction Rate Name of lab: Effects of temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration on Enzymatic Activity Introduction: Enzymes are the most important types of proteins‚ they act as catalysis (speed up chemical reactions). If enzymes didn’t exist‚ biochemical reactions would act to slowly and they couldn’t keep up with the metabolic functions. Enzymes have a three-dimensional structure that is really complex. This structure consists

solution would be put into the cuvette at precisely 30 seconds and so time would not have an effect on my results. I also used separate pipettes to measure out the starch‚ amylase and distilled water so that the solutions don’t mix together before the reaction should start. Also‚ I repeated each of my experiments two times to make sure I get accurate

Using these four passages and your own knowledge‚ assess the view that international diplomacy failed to achieve stability in Europe from 1919 to 1930. Initially‚ interpretation A presents the view that mutual pacts between Germany‚ Belgium and France helped peace in the region. These agreements would have allowed the possibility of future dealings as well as reducing post-war tensions; however‚ as interpretation D agrees‚ I believe this détente was an “illusion”. I believe the idea the agreements

Numerous reactions‚ catalyzed by a multi enzyme complex then occur‚ where the pyruvate is decarboxylated as shown in the reaction below.

Biology coursework The aim of this experiment is to investigate the affect of pH on the enzyme amylase. The amylase is used to break down the polysaccharide starch. Amylase is a digestive enzyme classified as a saccharidase (an enzyme that cleaves polysaccharides). It is mainly a constituent of pancreatic juice and saliva‚ needed for the breakdown of long-chain carbohydrates (such as starch) into smaller units. Amylase is also synthesized in the fruit of many plants during ripening‚ causing them
