Fermentation is a process performed by cells in the absence of oxygen to produce small amounts of ATP. During this process the six-carbon sugar glucose is broken down into two molecules of the three-carbon organic acid‚ pyruvic acid‚ coupled with the transfer of chemical energy to make adenosine triphosphate (ATP). Fermentation is used by many producers to make many of the commodities which we are used to today. Some of these commodities include yogurt‚ cheese‚ wine‚ bread‚ beer‚ rum‚ and even

the rate of oxygen uptake. Objectives : 1. To demonstrate the uptake of oxygen in respiration. 2. To measure the rate at which an organism respires. 3. To learn how to set up the apparatus for respirometers. Introduction : Respirometer A respirometer is a device that been used to measure the rate of respiration of a living organism. This can be measured by calculating the rate of exchange of oxygen and carbon dioxide. A simple respirometer designed to measure oxygen uptake or CO2 release

Design: Investigation of Fermentation Introduction Introduction Yeast (Saccharomyces)is a single-celled microorganism in the Fungi family. It anaerobically respires sugars to produce ATP‚ as well as the waste products ethanol and carbon dioxide gas. This process is known as fermentation. There are various factors that affect the rate at which yeast respires. Aim To investigate the effect of concentration of table salt (sodium chloride) on the rate of fermentation of sucrose using yeast‚ measured

you get 2 pyruvate – 3-carbon molecules NO O2 - Fermentation 1. Lactic Acid – your muscles ache because of the accumulation of lactic acid. 2. Alcohol Fermentation- ethanol is fancy word for alcohol. Alcohol fermentation is alcohol + CO2 O2 Aerobic * Respiration * Mitochondria * Matrix – Krebs Cycle – C6 – gives you 2 more ATP * Innermembrane- ETS – 34 ATP Mitochondria is only involved in the presence of oxygen. * Must know pyruvate for the test.

Bacterial Fermentation Secondary article Article Contents Volker Mu¨ller‚ Ludwig-Maximilians-Universita¨t Mu¨nchen‚ Munich‚ Germany . Introduction Under anaerobic conditions‚ in the dark and in the absence of electron acceptors‚ organic compounds are catabolized by strictly anaerobic or facultatively anaerobic bacteria by internally balanced oxidation–reduction reactions‚ a process called fermentation. In fermentation‚ the organic compound serves as both electron donor and acceptor‚ and adenosine

In biological processes‚ the immediate energy source is often in the form adenosine triphosphate (ATP). The nucleotide ATP maintains both catabolic and anabolic reactions. An example of

A molecule of water consists of one oxygen and two hydrogen atoms joined by covalent bonds. Water as a liquid is vital to existence and plays extremely important roles in many aspects of both plant and animal lives. These aspects include temperature control‚ support‚ chemical reactions‚ transport and protection. Without the ability to control our temperature‚ we as humans would not be able to survive in our natural environment. If our internal body temperature was to rise or fall even a few degrees

Role of energy in the body There are six main forms of energy- Chemicals Heat Electrical Light Nuclear Sound Energy can be measured or expressed by joules or unites of hear (kilocalorie). 1 kilocalorie= 4.184 kilojoules. Sources of energy- Protein 1g= 4 kcal Carbohydrate 1g= 4 kcal Fats 1g= 9 kcal In our bodies we need energy we need energy for everything we do‚ move our muscles‚ talk etc. Without energy we wouldn’t be able to do anything‚ energy is needed for our bodies to function

percentage of sugar will produce more fermentation. The original purpose of this experiment was to determine the amount of fermentation of 3 different fruit juices after adding a certain amount of yeast. By measuring the type of fruit juice (independent variable) the amount of fermentation as shown by the reduction of sugar (dependent variable).My hypothesis my hypothesis is that the fruit juice with a higher percentage of sugar will produce more fermentation. The experimental results supported my
