what is left is 2 pyruvates. Fermentation then takes place only in the absence of oxygen. In fermentation the pyruvate is converted into ethyl alcohol‚ through the oxidation of the 2 NADH molecules‚ which returns them to two NAD+’s (Freeman‚ 2011). Oxidation is the loss of an electron in this case H+. We used information from previous labs in which we tested

EXPERIMENT NO. 1 INTRODUCTION TO LAB INSTRUMENTS. 1. BREADBOARD We should be familiar to the following things about a breadboard: * What is a breadboard and what is it used for? * How does it work? * Setting Up. * Limitations. What is a breadboard and what is it used for? A breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). It was designed by

1. OBJECTIVES (a) To determine the equivalent circuit parameters of a 3-phase squirrel-cage induction motor from laboratory test data. (b) To determine the performance characteristics of an induction motor under load conditions. (c) To control the no-load speed of an induction motor. 2. INTRODUCTION 2.1 Three-phase squirrel-cage induction motors An induction motor is a transformer with a rotating secondary winding. It has two essential components: an outer stationary stator and an

solutions with varying pH Laboratory Notebook pH paper Background pH stands for potential hydrogen. This is a measure of the acidity or basicity of a solution. Acidic and basic are two extremes that describe a chemical property chemicals. Mixing acids and bases can cancel out or neutralize their extreme effects. The pH scale is a set of standard solutions whose pH is established by international agreement. A substance that is neither acidic nor basic is neutral. Solutions with a pH less than 7

Certificate Authority or Certification Authority (CA) is an entity‚ which is core to many PKI (Public Key Infrastructure) schemes‚ whose purpose is to issue digital certificates to use by other parties. It implies a trusted third party. 3. An attacker can create a certificate for any domain. This certificate will appear to be signed by a trusted CA. Thus‚ you will see

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

Alka-Seltzer Rocket Formal Lab Report Abstract In the Alka-Seltzer Rocket lab one was to experimentally determine how much (grams) Alka-Seltzer and water in mL‚ is needed to launch the rocket the highest/longest distance in cm. Also to experimentally determine the % NaHCO3 in the tablet using the information from the highest/longest distance. Calculate the error and % error of NaHCO3 in an Alka-Seltzer tablet and to determine the limiting reagent for the highest/longest distance traveled. Alka-Seltzer
