In the first part of the lab‚ we prepared a salivary amylase solution and aggregated acetic acid to detect the presence of mucin. Then‚ 4 test tubes were made of the following: Tube 1 = 3 ml starch + water + 37 degrees water bath; Tube 2 = 3 ml starch + saliva in water bath; Tube 3 = 3 ml starch (cooled)

When the plate is flooded with iodine‚ where there is a clearing then that bacteria can secrete amylase. There was a clearing only around Bacillus subtilis on the plate meaning that it can secrete amylase. Staphylococcus aureus and E. coli did not have this clearing meaning they can not secrete amylase. Casein agar is a complex that tests for the ability of a bacterium to secrete a proteinase enzyme that can break down the protein casein‚ which is

enzymes start work. There are two enzymes found in the saliva of the mouth‚ salivary amylase and lingual lipase. Amylase breaks down dietary carbohydrates such as monosaccharides‚ disaccharide sugars and complex polysaccharides (starch). Monosaccharide’s can be easily absorbed into the bloodstream so the others need to be broken down into these before they can be absorbed (Derrickson‚ Tortora 2006 p906). The salivary amylase starts to break down the polysaccharide starch found in the bread of sandwich

helps in digestion of food. The names of enzymes that help in digestion are: •Amylase: This enzyme helps in breaking down carbohydrates. It is found in saliva‚ pancreas and intestinal juices. •Proteases: It helps in digestion of proteins. It is present in the stomach‚ pancreatic and intestinal juices. •Lipases: Lipases assist in digestion of fats. It is seen in the stomach‚ pancreatic juice and food fats. Amylase I and II are secreted by the salivary glands initially and then by the pancreas

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

glands. The food is mechanically broken down. An enzyme named salivary amylase breaks starch into chunks of glucose called dextrins and maltose(disaccharide maltose). Once the food reaches the stomach‚ the acid in the stomach inactivates all salivary amylase. Carbohydrate digestion is not conducted the stomach for this reason. Before the food approaches the small intestine‚ the pancreas secretes pancreatic amylase. The pancreatic amylase digests starch into maltose. The enzymes maltase‚ sucrose‚ and lactase

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

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
