Hydrolysis of starch for fungal amylase Aspergillus Oryzae and bacterial amylase Bacillus Licheniformis at different temperatures. Maydelis Perez PI 4593042 Florida International University BSC 1010L‚ section UO9‚ March 6‚ 2013 Abstract Enzymes are very specific protein because they contain one active site on their surface that enable the substrate to bind to the enzyme and form the enzyme substrate complex and then release

effect of pH on the activity rate of salivary amylase? Dependent variable: activity rate Independent variable: pH Hypothesis: This is a paragraph or two where you explain your research question. You are going to say something like: "Salivary Amylase is a an enzyme that digests starch into di- and monosaccharides. Since it’s a salivary amylase‚ the enzyme works best at an alkaline pH of 7‚ in other words‚ the optimum pH is 7. At this pH‚ the rate of amylase activity will be at it’s highest. A

that Carb Cutter pills are effective at preventing amylase‚ an enzyme that breaks down starch‚ from digesting starch. This then prevents starch from converting into glucose and then to body fat. The carbs that aren’t absorbed then pass through the digestive tract and are excreted. From what we hear‚ the pill sounds like it will do wonders‚ but similar studies believe otherwise; “Studies by Mayo Clinic revealed that to decelerate the digestion of carbohydrate‚ you need between 4‚000 to 6‚000 mg

tract to monitor the digestion of his meal‚ I will be describing all major structures I go through. Digestion begins in the mouth. A brain reflex triggers the flow of saliva when we see or even think of food. Saliva moistens the food while the teeth chew it up and make it easier to swallow. Amylase‚ which is the digestive enzyme‚ found in saliva‚ starts to break down starch into simpler sugars before the food even leave the mouth. The nervous pathway involved in salivary excretion requires stimulation

(because it cannot pass through the intestinal walls to the bloodstream and‚ if it could would not be in a useful chemical state. The gut modifies food physically and chemically and disposes of unusable waste. Physical and chemical modification (digestion) depends on exocrine and endocrine secretions and controlled movement of food through the digestive tract. Mouth Mouth Food enters the digestive system via the mouth or oral cavity‚ mucous membrane lined. The lips (labia) protect its outer opening
