thing about the large intestine is that it produces vitamins which become absorbed. The bad thing about this structure is that bacterial infections can occur‚ and irritate the the large intestine. Finally‚ we are in the last stage of the human digestion processes‚ the rectum. I hope I’m getting paid a lot for this. There must be some sort of deal here‚ oops‚ sorry‚ we’re on the air! We are live in the rectum‚ where the feces is stored until it is eliminated from the body. Well folks‚ now you know

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

crackers for the presence or absence of starch and of reducing sugars. Also‚ to test the chewed cracker‚ the one that didn’t have a reducing sugar‚ for the presence or absence of a reducing sugar with the saliva in it. Adding on‚ another part of the objective is to determine the effect of amylase on starch. For the Chemical Aspects lab‚ the objectives were to test for the presence or absence of carbohydrates‚ lipids and proteins in several test samples. In the starch test‚ the objective was to find the
Premium Glucose Enzyme Fructose
reaction that breaks down starch molecules by systematically breaking off the maltose molecules from the ends of starch chains. The maltose is further broken down by another enzyme. Phosphorylase is an enzyme that systematically removes glucose molecules by consumes phosphoric acid to break the beta-1-4-glucosidic bonds in starch. The interaction of phosphate with the glucosidic bond results in the formation of glucose-1-phosphate and the loss of a chain unit in starch. In the reverse reaction the

Physical laws & the environment constrain the size & shape of organisms. 2. Form & function are correlated at all levels of organization. 3. Chemical energy in food is used to sustain form & function. 4. Many animals (& other organisms) regulate

graduated cylinder‚ 4mL of distilled water‚ 2 mL of starch solution‚ and 2 mL of the glucose solution‚ then pour it into cup number two. Then use the glass stirring rod to stir the solution in cup two. Then remove the dialysis tubing from cup one‚ set the cup aside for later‚ tie up one end tightly. Then test the tubing with distilled water for any leaks‚ then pour out the water. Place a funnel at the end of the tubing and then pour the glucose-starch solution into the dialysis tubing from cup two

ii)Distillation The peels of nendran variety of bananas are taken as they are rich in cellulose and are kept in hot oven at 338K and dried sample is taken and is dissolved in hot water for starch extraction through soxhlet apparatus. This solution is treated with amylase enzyme for hydrolysis of starch to occur. It is the subjected to fermentation process by inoculation of S.cerevisiae for 3 days at 300K which results in the production of ethanol. Ethanol from the solution is extracted by
