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

Osmosis coursework Aim: To investigate the effect of different concentration of a sugar solution on the amount of osmotic activity between the solution and pear pieces of a given size. Define osmosis: Osmosis is a net movement of water/ solution molecules from a region of high concentrated area to a region of lower concentrated area through a semi-permeable membrane which lets smaller molecules such as water through but does not allot bigger molecules like glucose to pass through. The molecules

The production of reducing sugars by acid of carbohydrate cereals powder‚ jams (total sugar content) and jams (reducing sugar content) were performed in order to study reducing sugar production. The study involved hydrolysis carbohydrate cereals powder and jams by immersing in boiling water at environmental temperature. Acid hydrolysis was carried out through reflux boiling for 20 minutes with 10ml 0f 1.5M concentrations of diluted sulphuric acid. Reducing sugars concentrations were determined

or sugar. Between these four foods two are positive for sugar which are apple sauce and carrot juice. Sugar is an organic molecule of carbohydrate and so is starch. The starch was positive in two of the foods which are cracker juice and carrot juice. Protein is its own organic molecule and only one food tested positive for protein and it is the turkey juice. Introduction The “Food Lab” was used to answer the question “What organic molecules will be found?” The organic molecules being sugar‚ starch

An investigation into the effects of sugar concentration on yeast activity Introduction: Yeasts are eukaryotic micro organisms belonging to the kingdom fungi. Yeasts live on sugars and produce ethanol and carbon dioxide as by-products. [James Mallory‚ 1984]When Yeasts are given water and sucrose they convert the sucrose into glucose then convert the glucose into carbon dioxide and ethanol following the following reaction: C₆H₁₂O₆ ( 2(C₂H₅OH + CO₂ [Brady Burkhart‚ Terrell Grayson and Eric Kimler

To Study the Filterability and Quality of Raw sugar for Refining ABSTRACT This study was particularly designed to evaluate the quality parameters of raw sugar which ultimately affect the filterability of raw sugar. It is a cane sugar which has been minimally processed and product of the first stage of cane sugar refining process which has some very distinctive characteristics. Filterability of raw sugars is one of the primary sugar quality parameters. To the refiner‚ the filterability of

In this lab we tested to see if the amount of sunlight exposed to the basil seed‚ would affect the growth. The null hypothesis for this experiment was that there would be no statistical difference between the green‚ yellow‚ and red basil seeds’ growth. Three alternate hypotheses are: If we expose the green seed to 48 hours of sunlight and the yellow seed to 24 hours of sunlight‚ then the green seed with grow more than the yellow. The opposite of this hypothesis would alternate 2. Another alternate

Can sugar be harmful to our bodies to the point that it causes early death or many diseases? A senior Dutch official has called for tighter regulation of sale and consumption of sugar‚ warning that is the “most dangerous drug of the time”. Sugar causes many disease such as fat deposits in the liver‚ diabetes‚ and the increase in risk of heart disease. Soft drinks and other sugary substances should carry tobacco — style warnings that sugar is highly addictive and dangerous‚ to consume. There

In the article “The Government Can’t Stop Sugar” by the Chicago Tribune‚ we learned about the many problems that sugar has caused. Sugar has led up to many disputes in the government‚ it also has caused many Americans to become addicted to it. Our love for sugar has led to unhealthy lifestyles‚ causing many Americans diseases and to become obese. The Chicago tribune argues that our sweet is killing us. They gave various studies‚ examples‚ and facts that persuades the reader into thinking that we
