Effect of Enzyme and Substrate Concentration on Reaction Rate by Zachary A. Poché Biology 155 Laboratory October 15‚ 2014 Lab Partners: Cade White‚ Hannah Ragas‚ Russheka Aremillion ABSTRACT In order to increase the reaction rate‚ substrates attach to the active site of enzymes which decrease the activation energy required to convert substrates to products. We examined the effect of enzyme concentration and substrate concentration on the overall rate of the reaction. To determine

6 November 2012 SUBJECT: Lab Report Analysis This memo proposes the observations and claims I collected from reviewing three different lab reports. Three fields of study are composed within this memo that includes Electrical Engineering‚ Environmental Engineering‚ and Petroleum Engineering. “Electrical Filters‚” (Electrical)‚ written by Joe Schmoe‚ is a lab report made by a student at a university. The College Board produced an environmental lab report named‚ “Monitoring Air Quality‚”

The temperature of water was determined by a thermometer. 1 cm stripped ends of the wires was hooked into the input posts on the back of the impendence converter. Lab tutor module was started after. B. Baseline heart rate The top of the container was covered with foil and the animal was allowed to sit quietly for 10 min. The trace was examined by pressing start. After that the baseline or the controlled

the acyl-enzyme is then hydrolysed by nucleophilic attack of serine on the peptide carbonyl group‚ collapse of the tetrahedral intermediate and the release of the amine component. Histidine 57 then acts as a general acid catalyst and draws a proton away from the water molecule. The OH- ion then attacks the carbonyl carbon atom of the acyl group which forms another tetrahedral intermediate which breaks down to form the carboxylic acid product. The release of this acid then frees up the enzyme to continue

Gbengon‚Sennie Microbiology Lab Case study # 5 November 1‚2012 1. What evidence suggests that the young graduate student has contracted what disease? Ans: The signs and symptoms the young graduate student presented‚ show evidence of Lyme disease. 2. What is the environmental pathway for the vector of this disease? Ans: The environmental pathway for the vector of this disease would be a forested habitat. The black-legged tick or the deer tick is the principle vector of this disease (Lyme

SCIE211 Phase 2 Lab Report Title: Speciation Instructions: You will need to write a 1-page lab report using the scientific method to answer the following question: • What would happen if a species within a population were suddenly split into 2 groups by an earthquake that creates a physical barrier like a canyon? When your lab report is complete‚ post it in Submitted Assignment files. Part I: Use the animated time progression of speciation to help you write up your lab report. Part II: Write

Are there any differences in the rate of metabolism of a dried yeast culture with differing carbohydrate sources? In the current practical that was undertaken the growth rate of yeast (S. cerevisiae) with differing carbohydrates sources : Glucose (C6H12O6)‚ Fructose (C6H12O6)‚ Lactose (C12H22O11)‚ Xylitol “(CHOH)3(CH2OH)2” and Water (H2O) as a Control were observed. “ Yeast are single-celled fungi which consist of more than one thousand different species which have been identified. The most commonly

The Catalase Lab Stephen Human Anatomy & Physiology 9/30/12 Problem- How do different environments affect the reactivity of catalase? Hypothesis- If more catalase is added then more oxygen (kPa) will be produced in a faster rate because there is more catalase to react upon. If less catalase is added then less oxygen (kPa) will be produced in a slower rate because there is less catalase to react upon. Variable- Independent- Amount of Catalase (Filter Paper) Dependent- Amount of
