Comparing the Rate of Fermentation of Yeast in Solutions with Different Concentrations of Glucose Brandon Bosley BIO 121 11/19/2013 Introduction: In our lab this week we tried to see how different amounts of substrates affect our organism‚ yeast‚ in its fermentation process. Yeast (Saccharomyces cerevisiae) is an organism that is cultured for the cells themselves‚ as well as the end products that they produce during fermentation. Yeasts are commonly known for the ethanol fermentation due

Yeast which is also known as Saccharomyces Cerevisiae is a unicellular eukaryotic Fungi means that is made up of one cell with a nucleus(“What is Yeast”).Yeast is a very practical product that is used in mainy way like when baking Yeast helps raise the dough and also yeast is used in the process of making wine.The Reason why yeast was chosen to was to see how yeast can metabolize different sugars and how much Co2 they release when when metabolizing.To test the yeast at the lab we used 4 different

known as the active site. The nature and arrangement of amino acids in the active site make it specific for only one type of substrate. Enzymes catalyze an unfathomable number of reactions by using a combination of only six basic mechanisms: (1) acid-base catalysis; (2) covalent catalysis; (3) metal ion catalysis; (4) electrostatic catalysis; (5) proximity and orientation effects; and (6) preferential binding of the transition state complex. Independent of the mechanistic characteristics taken to generate

oD 4.1 Respiration Why organisms undergo respiration What is respiration and why do we need it? Respiration is the process whereby energy is released from food molecules (most usually glucose). It takes place inside living cells‚ both eukaryotic and prokaryotic. The process takes place inside the cytoplasm and the mitochondria. Energy is used to synthesise adenosine triphosphate (ATP)‚ which acts as a short-term energy store in cells. All living organisms need energy to drive their

and Respiration Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat: Photosynthesis is the process in which certain life forms are able to use sunlight to create energy. This energy is created by making carbohydrates from carbon dioxide and water in the presence of chlorophyll. Plants release large amounts of oxygen into the atmosphere as they produce much more than needed during the photosynthesis process. Aerobic respiration is an

BIOLOGY A REPORT ON RESPIRATION IN INVERTEBRATES COMPILED & PRESENTED BY DEPARTMENT OF ANIMAL AND ENVIRONMENTAL BIOLOGY 2012/2013 SESSION COURSE: FSB201 (CELL BIOLOGY) COURSE LECTURER: DR. NOUTCHA DATE : 7TH MARCH‚ 2013 INTRODUCTION Respiration is one of the characteristics of ALL LIVING THINGS. In the simplest terms‚ "respiration" simply means "breathing". But more formally‚ the term depends on what type of respiration been referred to. Essentially‚ "respiration" refers to gaseous exchange

detoxifying hydrogen peroxide and preventing the formation of carbon dioxide bubbles in the blood. This laboratory exercise involves the use of an enzyme that will react with hydrogen peroxide. The enzyme is catalase and hydrogen peroxide (H2O2) is the substrate. The reaction is as follows: catalase 2H2O2 2H2O + O2 Ingested hydrogen peroxide is a poison‚ while external use of this substance is not. However‚ the generation of oxygen gas requires careful handling

Done by: Instructor: Introduction Respiration is the number of processes which leads to the oxidation of organic compounds to produce the energy. There are several types of respiration‚ and one of them is aerobic. During the aerobic respiration‚ human uses the oxygen from atmosphere and produce carbon dioxide. A cardiorespiratory system which includes lungs‚ heart‚ blood vessels and others is responsible for all the processes linked to the respiration and controlled by the nervous system. During
