two types of fuel‚ carbohydrates‚ and fatty acids. At the beginning of exercise the main source of fuel is carbohydrates‚ however the duration of the exercise progresses the carbohydrates deplete and fatty acids are needed to maintain the exercise. The type of fuel being used can be seen in the ratio called‚ respiratory exchange rate‚ or RER. An RER of 0.7 means that carbohydrates are being used for fuel‚ and a ratio of 1.0 means that only fatty acids are being used for fuel; of course‚ values can

Mr. Mihordea Motion of Atoms and Molecules lab summary In this lab the standard heat of combustion of magnesium was calculated by using the calorimeter. Also‚ the point of combustion of magnesium was to see how much heat would be released from fireworks such as sparklers. The concept of this lab was to find the difference in temperature from the beginning to end of combustion of magnesium and calculate the standard heat

Unknown Lab Report Unknown Organism #6 Ann Le (Phuoc) May 6‚ 2010 Dr. Carrington Microbiology Lab- MW 12:50 Le 1 I. Introduction My unknown organism #6 is Morganella morganii‚ which is a gram-negative bacillus rods commonly found in the environment and also in the intestinal tracts of humans‚ mammals‚ and reptiles as a normal flora. (3‚ 5) This bacterium Morganella morganii‚ was first discovered in the 1906 by a British bacteriologist named H. de R. Morgan. (2) Despite its wide

iron powder. Para-aminophenol crystallises out from the mother liquid which is subsequently centrifuged. Para-aminophenyl crystal is then reacted with acetic anhydride to produce pure paracetamol. The reactions are summarised as shown below: Lab scale manufacture Paracetamol can be easily prepared in the laboratory using phenol. Phenol reacts with sodium nitrate and separate para nitro phenol from outho nitro phenol. Then para nitro phenol is converted into para amino phenol using sodium

acetylsalicylic acid by esterification. Introduction: A pleasant‚ often fruity‚ odor is characteristic of some of the simpler esters. Ethyl butyrate smells similar to pineapples‚ the odor of n-propyl acetate is reminiscent of pears and isopentyl acetate has a strong banana fragrance. Esters are derivatives of the carboxylic acids and contain the following functional group: The synthesis of an ester can be accomplished in one of several ways. An esterification occurs when an alcohol and a carboxylic acid are

The Behavior of Proteins: Enzymes Enzymes are Effective Biological Catalyst Catalysis- speeds up metabolism to allow production of products. Enzymes- Highly specific and most efficient catalyst that speeds up metabolism or rate of reaction in organisms by factor up to 10^20 (globular proteins) Nonenzymatic catalyst- enhance by 10^2 -10^4 Ribozymes- acts for catalytic activity in RNA’s Kinetics versus Thermodynamics Standard free energy change- difference between the energies of the reactants

organisms are biomolecules. Today in lab‚ a series of tests were ran. Tested were the biomolecules of cells which are lipids‚ sugars‚ proteins and starch. The purpose of these tests were to test for the presences of cellular biomolecules. Some of the things that fat consist of are one glycerol and three fatty acids. Proteins are considered polymers. They are made up of smaller molecules called subunits. Now with proteins they contain a large number of amino acids that are joined together by a peptide

1 Measuring and calculating equilibrium constants Clearly‚ if the concentrations or pressures of all the components of a reaction are known‚ then the value of K can be found by simple substitution. Observing individual concentrations or partial pressures directly may be not always be practical‚ however. If one of the components is colored‚ the extent to which it absorbs light of an appropriate wavelength may serve as an index of its concentration. Pressure measurements are ordinarily able to measure

The study of metabolism reaches as far back as the thirteenth century. With it‚ things like the citric acid cycle‚ mitochondrial physiology‚ and diseases like diabetes have been better understood. The overall concept of metabolism is key in any biological field and it helps ensure the survival of an organism. It does so by converting things like food that we ingest into energy via a series of somewhat complex biochemical reactions. This energy can then be used for a multitude of things including
