Review Sheet Exercise 8 Chemical and Physical Processes of Digestion NAME Dane Wilson LAB DATE/TIME august 4th Carbohydrate Digestion 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

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

Lab 8 - Chemical and Physical Processes of Digestion (p.105) Introduction: In this lab‚ I will study how digestion of carbohydrates‚ proteins‚ and fats occurs. I will define Key Terms that describe what will occur in the experiments; I will conduct an experiment for each Activity and provide all resulting Data as well as answer Questions from each Activity. I will then provide a short Summary for what I learned in each Activity. Key Terms: Enzymes (p. 105) – Speed up chemical

The Digestive System Structure and Functions Jermaine Kendrick Vista College The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract). The alimentary canal is made up of the oral cavity‚ pharynx‚ esophagus‚ stomach‚ small intestines‚ and large intestines. In addition to the alimentary canal‚ there are

The Digestive System Why is it that 1 in 3 people perhaps even more regularly battles some kind of digestion problems? Understanding how the digestive system works will help to understand why digestive problems are so common. The digestive system is more than stomach and intestines. It is a system of organs that turns food into energy and is one of the most important functions the body performs. There are many reasons that cause so many people to suffer with digestive problems. Three of

Computer Simulation * A software program that runs on any computer that attempts to simulate some phenomenon based on a scientist’s conceptual and mathematical understanding of the given phenomenon. * The scientist’s conceptual understanding is reduced to an algorithmic or mathematical logic‚ which is then programmed in one of many programming languages (Fortran‚ C‚ C++‚ etc.) and compiled to produce a binary code that runs on a computer. * Have become a useful part of modeling

Digestive System Digestive system includes the stomach‚ liver‚ pancreas‚ duodenum‚ ileum and colon. What is a Digestive system? Digestion is a breakdown and transportation of the solid and liquid food into microscopic substances therefore theses substances are then transported into different areas of the body The digestive system is a set of organs which transforms whatever we eat into substances that can be used in the body for energy‚ growth and repair. Once the food has been

The principal structure of the digestive system is an irregular tube‚ open at both ends‚ called the alimentary (al-i-MEN-tar-ee) canal or the gastrointestinal (GI) tract. In the adult‚ this hollow tube is about 9 meters (29 feet) long Think of the tube as a passageway that extends through the body like a hallway through a building. Food must be broken down or digested and then absorbed through the walls of the digestive tube before it can actually enter the body and be used by cells The teeth

The digestive system is a group of organs that perform the process by which food‚ containing nutrients‚ is eaten and broken down into different components. This breakdown makes it possible for the digested material to pass through the intestinal wall into the blood stream. The digestive process contains many different steps that take place in many different organs.<br><br>The first step of digestion begins at the mouth‚ where the food enters the mouth. Saliva is secreted from the salivary glands
