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?

They’re two types of metabolism which are Catabolism (Aerobic Metabolism) and Anabolism (Anaerobic Metabolism). Catabolism (Aerobic Metabolism) occurs when there is plentiful supply of glucose and oxygen for the cells to use for cellular respiration (Aerobic Respiration happens eventually with the mitochondria in the cells producing A.T.P-Adenosine Triphosphate). Anabolism (Anaerobic Metabolism) will occurs after vigorous exercise when demand for glucose and oxygen cannot be met by the body‚ cells then

What is fermentation and why does it matter ? Fermentation is the process in which glucose is broken down in the absence of oxygen. Fermentation matters for many reasons. It’s important in muscles because it allows the muscles to keep getting energy from glucose even though oxygen can’t keep up with supplying. Fermentation also takes away the end products of glycolysis so that glycolysis can continue breaking down glucose and releasing energy. Fermentation is also important to the baking industry

Chapter 5 Assignment 1. What is energy? What are the three forms of energy? Energy is the capacity to do work. There are four types of energy according to the powerpoint. They are Kinetic energy (energy of motion)‚ potential energy (stored energy)‚ thermal energy (heat)‚ and chemical energy (potential energy of molecules). 2. State the First and Second Laws of Thermodynamics. Include entropy in your explanation. The first law states that energy can neither be created nor destroyed it can

cellular respiration (The process in which a cell breaks down sugar or other organic compounds to release energy used for cellular work). This process includes glycolysis‚ pyruvate oxidation‚ the kreb cycle‚ and the electron transport chain. The theoretical ATP output by this process is 36 ATP per glucose (C6H1206). Lipids are broken down to fatty acid chains and through a process called beta oxidation; the fatty acid chain is broken down to many acetyl-Co A‚ which then enters cellular respiration at the

about cycles. Respiration Cells in the body use ATP as a direct source of energy. The conversion of glucose into ATP takes place during respiration. There are 2 different types of respiration‚ the more common and frequent one is aerobic respiration which is the production of ATP for energy. The less common one is anaerobic respiration‚ the production of lactate during which the muscles have a limited supply of oxygen‚ and however keep working despite this. Aerobic respiration requires oxygen

of this lab was to gain a complete understanding around the rate of cellular respiration within multicellular organisms‚ also to research and understand how to use a CO2. Background: Living systems require free energy and matter to maintain order‚ to reproduce‚ and grow. Energy deficiencies cause disruptions at the population and ecosystem levels as well. 1 mol of H2O produces 1 mol of CO2 through cellular respiration. Autotrophic organisms capture free energy from the environment through the process

Cellular Respiration I/ Introduction - Cellular respiration is the cellular process whereby carbon-containing compounds are broken down through the series of reactions that result in the gradual release of energy. - Cellular respiration consumes oxygen (O2) and produces (CO2). Because oxygen is required so cellular respiration is aerobic. - Include metabolic pathways: glycolysis‚ transition reaction‚ the Krebs cycle‚ electron transport system and oxidative phosphorylation. - Overall reaction:

phosphorylation‚ and reduces three molecules of NAD and one molecule of FAD for use in Oxidative Phosphorylation. The cycle is preceded by Glycolysis‚ which also occurs in anaerobic respiration‚ and the pyruvate dehydrogenase complex‚ which occur in the cytoplasm and the mitochondrial matrix respectively. In aerobic respiration‚ glycolysis breaks down one molecule of glucose and two molecules of pyruvate‚ and gives a net product
