Biology Fermentation Practical "A comparison of the respiration of yeast in different sugar substrates" Aim: The aim was to compare the respiration of yeast in different substrates of sugars‚ i.e. between a monosaccharide (glucose) and a disaccharide (maltose) Theory: There are three types of Carbohydrates‚ monosaccharides‚ disaccharides‚ and polysaccharides. The two‚ which I will be looking at‚ are‚ monosaccharide (glucose) and the disaccharide (maltose) Classification and major properties of

Factors Affecting Fermentation of Glucose by Yeast Introduction: Fermentation is anaerobic respiration whereby food is altered into more simple compounds and energy in the form of chemicals is produced‚ an example being adenosine triphosphate (biology-online.org/dictionary/Fermentation). All this occurs with the lack of atmospheric oxygen. At the end of the day alcohol and carbon dioxide are the end products when yeast is used in the fermentation procedure. But end products like acetic acid

of factors that can contribute to the growth of a population and these trends can be seen in a number of species. It is generally believed‚ from an ecological perspective‚ that populations will display either an exponential of logistic growth rate. If optimal environments are consistently maintained with no biotic or abiotic limiting factors (excess food‚ excess space availability‚ optimum climactic environment‚ no predation‚ etc) then a population will grow in an exponential direction.

The Press can perform its true role as a guardian of the public interest‚ as a Watchdog and a source of all kinds of information‚ only in a democracy. The newspapers in India‚ for the most part‚ enjoy freedom of expression i.e. not State-controlled. Of course‚ all journalists and newspapers must behave within the law and must not infringe the regulations regarding libel‚ defamation; otherwise they would make themselves liable to penal code. While observing the limitations of the law‚ the newspapers

Modern society is built by the young for the young. It is a dynamic creation that does not give much consideration to the old‚ sick‚ handicapped or incapable. They are merely tolerated as so much liability or nuisance. So these hardly wanted people face many problems in their everyday living. The old‚ who were once young‚ helped to make the present society. Now they pay the price of their former neglect of the old. They themselves are neglected and unappreciated in turn. An old person does

Many seniors expect to live peacefully as they grow older; however‚ elderly suffer from social isolation which can consequently lead to health problems. There is not many organizations that help seniors socialize and be connected to the community. Lower birth rates and higher mortality rates mean that there is going to be older people living at an older age than younger individuals. The nation needs to provide a proper plan to give the elderly people the care they need to live a proper l Senior

It is estimated that this number will be more than triple in the next 50 years. This is since‚ the older population grows faster in practically all the regions‚ in the world than the total population‚ and that the difference in the rate of growths is increasing1.

THE EFFECT OF INHIBITORS AND MANIPULATION IN ENERGY PRODUCTION OF YEAST CELLS FOR GLYCOLYSIS AND FERMENTATION INTRODUCTION The aim of this experiment was to study the process of alcoholic fermentation in Saccharomyces cerevisiae (yeast cells) and measure the rate of Co2 production during anaerobic breakdown of the respiratory substrate‚ sucrose‚ in the yeast cells. The effects of an inhibitor on respiratory enzyme were also looked at. It is hypothesized that the five different reaction mixtures
