imitation of a caterpillar’s digestive tract using dialysis tubing and glassware. The first material in this experiment is a small beaker representing the head and crop of the caterpillar. This beaker is filled with both starch and the enzyme α-amylase. This enzyme digests the starch found in the leaves the caterpillar is eating‚ which breaks it down into glucose. The opening of the soaked dialysis tubing represents the opening between the crop and intestine‚ so you fill the tubing with the solution

ENZYME LAB REPORT 1. In your own words‚ define objective qualitative and objective quantitative data. DO NOT USE EXAMPLES AS YOUR SOLE DEFINITION. (3) There are two different types of information that can be obtained from research. The types of information that can be obtained are quantitative and qualitative data. Research results are considered qualitative when the results can be answered with a simple statement of yes or no. Qualitative data does not attempt to give a numerical value; instead

Pancreatic Amylase- Enzymes found in the pancreatic juices and saliva. Bile acids- made in the liver and are responsible for emulsifying fats Activity 1 and Activity 2– Assessing Starch Digestion by Salivary Amylase: In this exercise‚ we will watch how salivary amylase (enzyme) works on a substrate starch and produces the subunits maltose and glucose. Data: Please submit Data for Activity 1 and 2. Please answer the following questions 1. What ph allowed the highest amylase activity and

people are looking for any alternative to lose weight (Anonymous 2011). If someone told you that they knew of a weight loss pill that actually works‚ would you consider it? A new study has proven 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

Hint: What variable was changed in the procedure? a. maximum of amylase is at pH 7.0 (tubes 2 & 5‚ brownish red) and pH 9.0 showed little activity (tubes 6 & 7‚ green) Which pH buffer allowed the highest amylase activity? a. 7.0 Which tube indicates that amylase was not contaminated with maltose? a. 3 - showed water Which tubes indicate that the deionized

The following questions refer to Activity 1: Assessing Starch Digestion by Salivary Amylase. 1. At what pH did you see the highest activity of salivary amylase? Why? 7.0 because that is when the salivary is most effective and it breaks down carbohydrates. 2. How do you know that the amylase did not have any contaminating maltose? We used a negative control to see if there is any amylase in the maltose. 3. What effect did boiling have an enzyme

Place 4 mL of amylase solution in the fifth tube. Place all of the tubes in the 37°C water bath for 5 minutes. Obtain 5 clean droppers and label them 1-5. (To avoid contamination of these solutions‚ you will use a separate dropper for each mixture.) 2. Tube 1 will be your control and it will not contain any enzyme. Remove the tubes from the water bath momentarily‚ and quickly add 3 drops of the warmed amylase solution to tube 2‚ add 6 drops amylase to tube 3‚ and add 10 drops amylase to tube 4. Mix

hydrochloric acid was used in the second test. The enzyme involed in this test is salivary amylase which can found in saliva. Salivary Amylase‚ is called ptyalin it’s to break down starch to sugar. Things we ate is broken down in mouth by amylase. Amylase hydrolysed starch into a reducing sugar which can give beneduct test a positive result. Body temperature is the optimal temperature for the action of amylase. Enzymes are catalysts for any reactions. They provide an alternative way of lower activation
