Ben Grygiel Professor Sides ENG-101-D260 1 September 2013 “Observing the Ordinary” Why do people tend to feel attached to “things”? This is a very good question that needs some thought behind it to give you a clear understanding why people feel this way. It’s in our nature to show emotions. If you think about it‚ everything we do in our lives we are showing some sort of emotion or feelings. When I think of people being attached to “things” the first thing that pops in my head is little kids

* Would yeast produce more carbon dioxide with the presence of sugar at room temperature or in an incubator? | -Observing Cellular respiration in yeast cells. | Yeast Lab Background Information: Yeast is a tiny unicellular fungus that obtains energy from outside sources (a heterotroph) mostly sugars in order to grow and reproduce. Yeast is often used in bread dough to make the dough rise. With the presence of oxygen a yeast cell creates energy by performing cellular respiration and

Lab Report: Understanding Photosynthesis Gen Biology Lab Abstract: This lab was called photosynthesis: understanding photosynthesis. It is a highly complex process that needs to be broken down in many steps to understand how it works. This lab covers the big components in photosynthesis including carbon dioxide intake‚ light consumption‚ and varying pigmentation. Introduction: Photosynthesis is a huge concept to learn and understand in the field of biology. Plants have their own special

not exist (Lab Manual 3 pg. 1). They help in many different ways that are useful to the body of living organisms. Enzyme are used to speed up chemical reactions (Lab Manual 3 pg. 1). Through this process‚ they are considered very unique because they are not altered or consumed within the reaction (Lab Manual 3 pg. 1). This is why enzymes are considered biological catalysts. They also do not alter the equilibrium of a chemical reaction nor the amount of free energy that is released (Lab Manual 3 pg

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

Term 2011 Lab Number: 3 Title: Cell Energetics: Enzyme Role in Biological Reactions Name: Brandon Moore Student Number: 100819124 Lab day and time: Wednesday pm Date: Wednesday November 23‚ 2011 Introduction Enzymes are a key aspect in our everyday life and are a key to sustaining life. They are biological catalysts that help speed up the rate of reactions. They do this by lowering the activation energy of chemical reactions (Biology Department‚ 2011). In chemical reactions

Harris October 18‚ 2011 Biology Lab report Proteins are very important throughout the body. They have a lot of functions in cells. Antibodies are proteins that help cells rebuild the cells when they are destroyed. Transport proteins move substances from one place to another. Regulatory proteins control cellular metabolism in a way that cells throughout the body can have the right amount of glucose in the blood. A common protein is an enzyme; in cells they speed up chemical reactions. For an example

19th 2013 SBI 4U INTRODUCTION: The cellular activity of all organisms is controlled through the use of enzymes. An enzyme is a special type of biological molecule‚ usually a protein‚ which speeds up a chemical reaction; most are soluble in water or a dilute salt solution. There are about 4000 different enzymes in a typical living cell. If even one of these enzymes is missing or defective‚ the results can disastrous. Enzymes have a unique three dimensional shape‚ and this shape determines

Theory: Panacetin is an analgesic (pain reducing) and antipyretic (fever reducing) drug that is sold in drug stores. However‚ there is a suspicion that this bottle may be counterfeit‚ not containing the chemicals that it should. Panacetin should be made up of about 50 percent

Title: Esterification Objective: To synthesis 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
