Lab: Cellular Respiration in Yeast Lab Report Form Your Name: Katlin Moore “What do you think? – What do you know?” Questions: In this lab‚ we will investigate the effect of sucrose concentration on the rate of cellular respiration in yeast. Under specific conditions‚ yeast will convert sucrose into glucose and then use this glucose in cellular respiration. Yeasts have been used by humans in the development of civilization for millennia. What is yeast? How have humans used yeasts?

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

Enzyme Lab Marcus James. December 20‚ 2013 HL Biology 3 Period 1 Purpose and Background The purpose of this lab is to explain how enzymes act as catalysts for biological reactions in different temperatures. This lab relates to enzymes‚ proteins‚ and substrates; that we learned in class. The union of the enzyme and the substrate is called the enzyme-substrate complex. The make-up of an enzyme is proteins and made up of chains and amino acids. Enzymes

PHOTOSYNTHESIS LAB Alyssa Wright VARIABLE: LIGHT INTENSITY AIM: to investigate the effect of light intensity (lux) on the amount of oxygen produced (number of bubbles) HYPOTHESIS: I predict that the rate of oxygen produced increases‚ as the light intensity increases‚ but only to a point. I predict this will happen because the plant will have enough carbon dioxide and water to keep up with the amount of light that there is. When there is less light intensity‚ photosynthesis will happen

Enzyme Activity Lab Objective: To determine the effect of temperature‚ PH and enzyme concentration on catalase activity. Introduction: What is an enzyme and how the enzyme works. Any of a group of complex proteins or conjugated proteins thatare produced by living cells and act as catalysts in specific biochemical reactions. The system in which enzymes work is often referred to as the ’lock and key’ system it’s where the enzyme and the substrate lock together. The substrate then unlocks into

your mass to 2 decimal places on your lab sheet. 4. Zero the balance. 5. Add 3-4 grams of zinc to the vial and determine the mass of the zinc. Record on your lab sheet. 6. Go to one of the burets set up around the classroom. 7. Look at the buret and record the volume on your lab sheet. 8. Add 10 to 15mL of acid to your vial and record the ending volume on your lab sheet. 9. Make a drawing in the space provided of the vial and its contents on the lab sheet. Be sure to label all the chemicals

PROJECT REPORT ON READYMADE GARMENTS By: Dr.R.Suresh Kumar‚ Chartered Engineer 1. Introduction This project profile is based on manufacture of readymade garments such as shirts‚ trousers tops‚ ladies suits (Salwar kameez and nighties). The demand of readymade garments is increasing day by day due to urbanization of the cities. The garments are very simple to manufacture and easily marketable both in urban

Lab Report: Enzyme Lab Your Name: Samantha Butcher Purpose of this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? It is going to explain how a liver’s enzymes break down substances that could be harmful.| Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. Give your reasons and outline any assumptions that lead

Biology 20 IB Design Lab Does increasing or decreasing the ph level of a 3% concentration H2O2 (l) solution affect the amount of oxygen released between 15.0ml of the solution and a 5g sample of liver? The reaction is measured by the difference in mass of a balloon that is used to capture the amount of gas released by the catalase enzyme found in liver reacting with a basified 3% H2O2 (l) and an acidified 3% H2O2 (l) . Chemical reactions occur when two or more molecules interact and the molecules
