Question How will the addition of different pH buffers to amylase affect the rate of starch digestion measured using starch and iodine? Introduction Amylase is an enzyme found in human saliva and pancreas. It is the digestive enzyme that is needed to breakdown starch molecules. Amylase must be kept at certain conditions to function at its optimum level. This experiment will explore the effect of pH (1‚ 4‚ 7‚ 10‚ and 14) on the function of amylase by using starch and iodine. Usually iodine has a orange-yellow

topic can understand the nature of the experiment. A good introduction is clear and concise. Carbohydrates and proteins should be explained in terms of their structure and major functions in cells. Your intro should end with a brief overview of the amylase experiment‚ including your hypothesis and predictions about what expect will happen in each treatment group of the experimentThe introduction is a statement of the subject and objectives of the experiment and presents your hypothesis.

digested is expelled. Digestive anatomy includes: Mouth = entrance to gastrointestinal (GI) tract‚ contains: teeth- cuts and grinds food to increase its SA to improve the rate of digestive reactions salivary glands- 3 pairs that lubricates food with saliva‚ containing salivary amylase (breaks starch into disaccharides) and antibacterial enzymes. Saliva dissolves some food. taste buds- identify the type and quality of food. Food dissolves in saliva and moves into the taste pores. Receptor

enzyme‚ Amylase which is used to break down carbohydrates will work the best when heated at 40°C. Also‚ as the temperature increases the reaction rate of amylase increases too. However‚ the reaction rate of amylase will start decreasing when the temperature reaches the enzyme’s optimal temperature. Many enzymes are specific for a certain substrate. For example‚ lipase is a specific enzyme for fat substrates and protease‚ a specific enzyme for protein substrates. In the same way amylase is a specific

Practical: The effect of pH on enzyme activity Rationale Amylase is an enzyme involved in the digestion system which catalyses the breakdown of starch into sugars. It is not only present in human saliva but also in the pancreas‚ where it hydrolyses dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy. pH has an effect on the activity of all enzymes‚ including amylase. As the pH level increases‚ the enzyme activity increases

Title: Investigate the breakdown of starch at different temperature AIM This experiment has been done to investigate the action of the enzyme amylase on the breakdown of starch. MATERIALS These were the materials used: four starch/ agar plates‚ a marker pen‚ 1mm graph paper ruler‚ 8mm cork borer‚ forceps and template for cutting holes‚ 1% Amylase‚ water‚ incubator set at 5‚ 20‚ 40 and 60 degree Celsius. METHOD This was the experimental procedure carried out: the materials above were collected
