Question: Effects of pH on amylase activity Introduction: Amylase is an enzyme that is in human’s saliva as well as the pancreas. Enzymes are biological catalysts that speed up a chemical reaction. They break down complex molecules into simple ones. In this case‚ amylase converts starches (complex molecule) into simple sugars. That is why foods like potatoes for example‚ may taste sweet to us‚ because they contain starch. The optimum pH for pancreatic amylase is the pH of 7. In the experiment

for the pH concentration experiment were put together by using a 10ml-graduated cylinder to obtain 4ml of each pH buffer to insert into cuvettes‚ a micropipette was then used to obtain 0.5ml of catechol and 0.5ml of the catechol oxidase. The pH buffer was made first to avoid any denaturation of the catechol oxidase. Our positive control for this experiment was pH 7 because that is the pH level of most cell membranes in the cytoplasm (Whitson‚ 2016.) Our negative controls varied for each pH buffer

In his Huffington Post Blog‚ “What Really Happens When We Use The R-Word‚” the firm activist explains why this now commonly used word is always meant as a “euphemistic put-down”‚ and how it should never be used to define an individual with a disability. Instead‚ the word should be disposed of‚ and replaced with an alternative

Blood will Have Blood “These deeds must not be thought / After these ways; so‚ it will make us mad”(II‚ ii‚ 32-33) Translation today: A guilty conscience can make a man go crazy. In the play Macbeth‚ this is a recurring theme throughout one of Shakespeare’s most famous tragedies. There are many different images that help contribute to this theme such as sleep/sleeplessness‚ water‚ & children‚ but the most significant image would probably that of blood. Throughout

studying the effect of pH on catalase activity. Catalase by scavenging hydrogen peroxide to water and oxygen is an important enzyme of cell defense mechanisms against oxidative stress in all living organisms (Dat et al.‚ 2003). Cells use catalase because it is the most efficient enzyme as an antioxidative enzyme which lowers hydrogen peroxide or superoxide to accumulate to toxic levels in plant growth (Bowler et al. 1992). The formula that involves catalase as the enzyme is . pH is a measure of the

Title : THE EFFECT OF PH ON THE ACTIVITY OF CATALASE Aim : To study the effect of pH on the activity of catalase. Introduction : Catalase‚ an enzyme found in many different tissues‚ catalyses the breakdown of hydrogen peroxide into water and oxygen. 2 H202 → 2H20 + O2 Hydrogen peroxide is a toxic substance that can be formed during aerobic respiration and catalase removes this product. The activity of catalase can be measured by finding the rate of oxygen release from hydrogen peroxide

The reason why I think this could be a limitation is because each solution has an extreme acidic pH level like 1 or 2. As a result‚ I speculate the supreme acidity of the solution could negatively affect the pH measurer that could make it lose the originality to measure the right pH level for later product. Hence‚ it is crucial to have the pH measurer calibrated in a buffer solution so that the measurement can have a high accuracy
