down sugars into carbon dioxide and ethanol which is very important in many fields such as biofuel‚ industrial‚pharmaceutical and others. Amylase is an enzyme that break down starch/amylose in plants. Corn kernel contains starch‚ sugars and cellulose. This experiment focused on the effect of amylase on corn extract in respect to the rate of fermentation. Since amylase breaks down starch‚ the part of corn that contains the most starch should have the fastest rate of fermentation and the greatest amount

There was a controlled and an experimental substance. The controlled substance was the one with starch in the dialysis bag‚ and the experimental substance was the one with starch and amylase in the dialysis bag. Both had the same solvent outside of the bag (Lugols and Distilled Water). The color change differed from inside and outside the bag as time went on‚ and at the end of the 45 minutes‚ the two bags had changed colors. The solute in the controlled substance had a darker color to it‚ with it

activate other enzymes (Huether & McCance‚ 2012). For example‚ activated trypsin then activates chymotrypsin‚ amylase‚ lipase‚ and elastase. This further explains why patient J.A.’s blood findings reported elevated serum amylase and lipase. Although‚ elevated serum amylase concentration is characteristic of pancreatitis‚ it is not used to confirm diagnosis; however‚ an elevated serum amylase is the primary diagnostic marker for acute pancreatitis (Huether & McCance‚ 2012). Furthermore‚ the activation

absorbed at various sections of the alimentary canal . The first digestion process starts at the mouth in which cooked starch is reduced into simpler sugars by the action of ptyalin. Digestion of the remaining cooked starch is completed by amylase in the small intestine where duodenum and pancreas take part. Absorption of simpler sugars as the products of digested starch‚ take place in the small intestine as well. The digestion of proteins starts in the stomach in which protein molecules are

temperature is increased. With each 10oC increase in temperature‚ the rate of reaction of the enzymes will double. This is because as the temperature increases the enzyme is coming closer to its optimum conformation. At its optimum temperature the alpha amylase will be at its most efficient. But the downfall of increasing the temperature of a reaction is‚ once the enzyme temperature is raised above its optimum temperature its activity will immediately decrease. This is because raising the enzyme above its

Amylase is a very important enzyme located in the saliva and pancreatic juices that hydrolyses (break down) starch and glycogen into more simple and readily digestible forms of sugar. Enzymes are biological catalysts that increase the rate of biological reactions. Enzymes are produced in living cells and are involved in speeding up biochemical reactions. They have an active site to which specific substrate binds. They increase the rate of reactions by decreasing the amount of activation energy meaning

C. Calculus Formation Relationship with Plaque: * Calculus is formed by the deposition of calcium and phosphate salts in bacterial plaque. These salts are present in salivary and crevicular fluids. * Plaque mineralization begins within 24-72 hours and takes an average of 12 days to mature. * Calculus contributes to the disease by providing foci for plaque accumulation. It is not the causative or etiologic factor‚ plaque is. * Calculus is porous and can act as a reservoir or nidus

KUROSAWA a rice disease that is known as the ‘foolish seedling’-disease in Japan. The plants grow extremely fast‚ look spindly and pale and break off easily. KUROSAWA detected that the reason for this abnormal growth is a substance that is secreted by a parasitic fungi (Fusarium moniliforme = Gibberella fujikuroi). It was termed gibberellin.
