enzyme that involved in the reaction is salivary amylase. The action of amylase on starch is with the mixture of IKI (iodine and potassium iodide test).Starch solution will have a blue-black colour in the mixture but no changes in colour for maltose solution. When hydrochloric acid (HCl) is added to the starch solution‚ the color will

Effects of pH on fungal amylase activity BI 211 November 25‚ 2011 Introduction In recent years‚ the uses of microorganisms have become a huge importance to industry and sparked a large interest into the exploration of enzyme activity in microorganisms. Amylase is one of the most widely used enzyme required for the preparation of fermented foods. Apart from food and starch industries‚ in which demand for them is increasing continuously‚ amylase is also used in various

are amylases? Amylases are enzymes that break down starch or glycogen. Amylases are produced by a variety of living organisms‚ ranging from bacteria to plants and humans. Bacteria and fungi secrete amylases to the outside of their cells to carry out extracellular digestion. When they have broken down the insoluble starch‚ the soluble end products such as (glucose or maltose) are absorbed into their cells. Amylases are classified based on how they break down starch molecules i. α-amylase (alpha-amylase)

What amount of amylase is the best to produce a better reaction with starch? A 1% solution of amylase‚ made from 0.15g of amylase added to 15ml of water‚ a 2% solution of amylase made of 0.3g of amylase added to 15ml of water‚ and a 0.5% solution of amylase made of 0.75g of amylase to 15ml of water were created. A 0.25% starch solution was also created‚ and 3ml was added to each of the 4 test tubes. 1 drop of iodine was added to each test tube. 4ml of the 1% solution was added to the first test

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

Abstract The researcher is conducting this experiment to find the optimum temperature and pH for starch on amylase. The experiment was carried out in one day. The researcher and a partner did the experiment based on a lab manuel from class. Data was collected from the experiment and to be displayed on graphs. Then the optimum pH and temperatures were to be calculated based on the findings. The hypothesis was disproved due to the optimum pH of 5 but the other findings supported the hypothesis of

FORM CLASS: L6 3 SUBJECT: Biology TITLE: Enzymes AIM: To investigate the effect of substrate concentration on the enzyme amylase INTRODUCTION: Enzymes are perhaps one of the most important proteins of the human body. Enzymes such as amylase‚ an enzyme that breaks down carbohydrates‚ work by means of surface catalysis. In other words‚ the surface of the enzyme enables other molecules to react in a manner they would not be able to without
