Bio Lab Report In part II of the Organic Compounds in Foods lab‚ we to examining whether or not the starch in the saltine cracker can chemically break down in sugar with the presence of salivary amylase‚ which is an enzyme found in your mouth which assists in digestion. My group and I were instructed to obtain a saltine cracker from our teacher and chew on it for approximately 2 minutes. After concluding the chewing‚ we then grabbed a beaker and spit our slimy and chewed cracker into it. Subsequently

CHEM 2213 Lab 25 Title: The Detection of Fats‚ Proteins‚ and Carbohydrate in Foods Purpose: The purpose of this lab is to perform several general tests which help in identifying fats‚ protein‚ and carbohydrates in food. Procedure: Part A- Tests for Detecting Carbohydrates In this part you will conduct the molisch‚ benedict‚ and iodine tests. Purple in the molisch test indicates a positive test. Benedicts test will result in a brick red/brown color for a positive test. For the iodine tests

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

Do Fats Digest More Slowly Than Carbohydrates and Proteins? The foods we eat are classified into six elementary groups: carbohydrates‚ fats‚ proteins‚ vitamins‚ minerals‚ and water. These foods are broken down into various nutrients during digestion. The time taken for the body to extract nutrients and the complexity of the digestion process depend on the molecular nature of the food eaten. Fat molecules seem more complex than the others so its digestion often takes a longer time. Types of Fat Fats

similar subunits called monomers. There are four categories of biological macromolecules that provide energy and structure to living organisms and their cells. The four types of macromolecules are: · carbohydrates · lipids · proteins · nucleic acids · Compare the structure and function of carbohydrates‚ lipids‚ proteins‚ and nucleic acids. lipids Fat molecules are made up of carbon‚ hydrogen‚ and oxygen atoms. These macromolecules are made up of smaller molecules‚ one glycerol and three fatty

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity

bio gas Co-digestion of Biomass for Methane Production: Recent Research Achievements Wei Wu ABSTRACT Anaerobic digestion (AD) is a process by which microorganisms break down biodegradable material in the absence of oxygen. Anaerobic digestion can be used to treat various organic wastes and recover bio-energy in the form of biogas‚ which consists mainly of CH4 and CO2. A great option for improving yields of anaerobic digestion of solid wastes is the co-digestion of multiple substrates. Numerous

PEES 4200W- Physiology of Exercise Lab #2: Metabolism and Energy Expenditure 1. The Respiratory exchange ratio is the ratio of the volume of carbon dioxide produced and oxygen consumed. The ratio indicates the energy that the subject is expending for indirect calorimetry‚ how efficient the subject ’s body is at utilizing the oxygen inhaled‚ as well as the main substrate being used for energy during varying intensities of exercise. During rest the volume of carbon dioxide was 0.73L/min‚ the volume

Background: Techniques used were in accordance with NMU Professor Dr. D. Becker’s lab manual (ISBN 0-390-53911- 2; McGraw Hill). Changes in protocol or interpretation are noted where they were implemented‚ but strict adherence to the manual prevailed. Materials and Methods: Microscope‚ incubator‚ and deionizer functioned correctly throughout testing period‚ with stains‚ dishes‚ agars‚ and test reagents readily available. Lab procedures are considered orthodox and usage thereof is noted chronologically
