Hydrolysis Report Bile Esculin Hydrolysis‚ Starch Hydrolysis‚ UreaHydrolysis‚ Casein Hydrolysis Hydrolysis Report Introduction Hydrolysis is a chemical reaction that uses water to split complex molecules. The water molecule H2O is split in the mechanism of hydrolysis‚ hydrogen cations and hydroxide anions. When the enzyme catalyzes its reaction inside the cell‚ it is referred to as intracellular hydrolases. When the enzymes secreted from the organism to catalyze reactions outside the cell‚ it

Experiments investigating the effect of a particular factor on an enzyme-catalysed reaction are commonly used as assessed practicals in Biology. The reason for this is there are a number of factors that can be investigated‚ and therefore‚ a number of factors that can also be controlled. From our lecture‚ we are aware that the following can affect the rate of reaction: 1) Temperature: a. Independent variable: A range of temperatures should be investigated‚ with particular attention

together by glycosidic linkage and known as polysaccharide‚ that is polymers of sugar. Saliva that contains salivary amylase enzyme‚ which breaks down the glycosidic linkage between glucose that found in starch and hydrolyzes starch into glucose at optimum temperature of 37°C‚ that is similar to human body temperature and show positive results to Benedict’s test The salivary amylase enzyme is denatured at 95°C as the enzyme lost in structure. In the experiment‚ test tube 1 and 4 is added with saliva

Effect of different temperatures on the rate of an enzyme controlled reaction I will place starch and amylase into five water baths which are at different temperatures‚ and record the time it takes to break down the starch in the solution. Independent variables The independent variable is what I am going to change in my experiment. In this case it is the temperature of the water in the five water baths- 10‚ 25‚ 40‚ 55‚ 70 degrees Celsius Dependant variable This is what will stay the

Increase the sucrose activity. 19. Referring to the table above‚ specifically state where in the intestine sucrase is likely most active. duodenum 20. Salivary amylase‚ an enzyme in saliva that breaks down starch‚ has an optimal pH of 6.7- 7.0. Explain why salivary amylase is active in the mouth‚ but becomes inactive in the stomach. Salivary amylase is an enyme that’s active in the mouth in order to break down starch into glucose it carries it function out in the environment where the PH is 6.7- 7.0 however

with starch. The enzyme that we are going to use is called amylase. We are going to test this enzyme with starch. By mixing amylase and starch solutions together under different temperature conditions‚ we can record the rate of reaction by taking a sample out and test it with iodine solution to see if there is any remaining starch present. We have to use the enzyme amylase because enzymes will only work on a specific substrate i.e. amylase will work on starch because of its special shape of active

still the most important detergent enzymes. Lipases decompose fats into more water-soluble compounds. Amylases are used in detergents to remove starch based stains. 2. Starch hydrolysis and fructose production The use of starch degrading enzymes was the first large scale application of microbial enzymes in food industry. Mainly two enzymes carry out conversion of starch to glucose: alpha-amylase and fungal enzymes. Fructose produced from sucrose as a starting material. Sucrose is split by invertase

following enzymes is found in the mouth? A) lactase B) maltase C) pancreatic amylase D) salivary amylase 10. Which enzyme digests carbohydrates in the stomach? A) salivary amylase B) pancreatic amylase C) amylose D) None‚ carbohydrates are not digested in the stomach. 11. In the absence of carbohydrate‚ ________ are produced from the incomplete breakdown of body fat. A) amyloses B) amylases C) ketones D) bacteria 12.

experiment. What effect did pH level have on the enzyme? It partially allowed the enzyme to do its job because there were positive signs of both starch and its reducing sugars. What effect did boiling and freezing have on the activity of amylase? Boiling did not allow the breakdown of starch because the reduced sugars were not present and the starch was where the freezing showed a ++ for the reducing sugars and a negative result in the starch showing that it reduced the starch.
