Physiology & Anatomy Lab SC 145L Anatomy & Physiology I Lab Chemical and Physical Processes of Digestion Introduction: In this lab‚ we will see how different chemical processes occur as we observe how different enzymes digest different substrates and produce subunits. Key Terms: (found in bold in Lab Manual) Please define all bold terms in your own words: Enzymes- Large protein molecules made by your body cells. Catalyst- Without becoming part of the substance it will change the rate

Question: Effects of pH on amylase activity Introduction: Amylase is an enzyme that is in human’s saliva as well as the pancreas. Enzymes are biological catalysts that speed up a chemical reaction. They break down complex molecules into simple ones. In this case‚ amylase converts starches (complex molecule) into simple sugars. That is why foods like potatoes for example‚ may taste sweet to us‚ because they contain starch. The optimum pH for pancreatic amylase is the pH of 7. In the experiment

10 mmol/L | Albumin | 30 g/L | Glucose | 12 mmol/L | Amylase | 5000 U/L --- Normal Range: 60-180 U/L | Serum: Comment: The diagnosis of acute pancreatitis is based on the clinical history‚ evidence of inflammation is known usually by computerized tomography (CT scan) and the finding of a high serum (or sometimes urinary) amylase activity. It is effectively a diagnosis of exclusion: the finding of a very high serum amylase activity is very suggestive but is not on its own diagnostic

The effect temperature has on the activity of the enzyme α- amylase. Introduction Enzymes are a biological catalysts‚ which means that they speed up the chemical reactions in living organisms. Almost all of enzymes are energized protein molecules that catalyse and regulate nearly all biochemical reactions that occur within the human body. The reason in which enzymes are sensitive to heat‚ pH and heavy metal ions is because they are made up of proteins. The food we eat is turned into energy by enzymes

LAB 10: NAME: DaeNia La Rodé DATE: 25TH January‚ 2011. FORM CLASS: L6 3 SUBJECT: Biology TITLE: Enzymes AIM: To investigate the effect of substrate concentration on the enzyme amylase INTRODUCTION: Enzymes are perhaps one of the most important proteins of the human body. Enzymes such as amylase‚ an enzyme that breaks down carbohydrates‚ work by means of surface catalysis. In other words‚ the surface of the enzyme enables other molecules to react in a manner they would not be able to without

Lab Report 8 April 15th Exercise 8: Chemical and Physical Processes of Digestion Lab Report Questions Activity 1 What is the difference between the IKI assay and Benedict’s assay? IKI assay detects the presence of starch‚ and the Benedict assay tests for the presence of reducing sugars as well as IKI turns blue black whereas Benedict is a bright blue that changes to green to orange to reddish brown with increasing levels of maltose What was the purpose of tubes #1 and #2? Why are they
