Are there any differences in the rate of metabolism of a dried yeast culture with differing carbohydrate sources? In the current practical that was undertaken the growth rate of yeast (S. cerevisiae) with differing carbohydrates sources : Glucose (C6H12O6)‚ Fructose (C6H12O6)‚ Lactose (C12H22O11)‚ Xylitol “(CHOH)3(CH2OH)2” and Water (H2O) as a Control were observed. “ Yeast are single-celled fungi which consist of more than one thousand different species which have been identified. The most commonly

Fats are put away in our fat cells as triglycerides‚ much the same as how glucose is put away as glycogen in our liver and muscles. Triglycerides are made of three immersed unsaturated fats. Keep in mind an unsaturated fat is only a long chain of carbons with hydrogens joined. Unsaturated fats are dependably a considerable number

result in the production of ATP? Glycolysis‚ and oxidative phosphorylation b. How many ATPs (total) are produced for every glucose molecule that undergoes cellular respiration? 38 ATPs c. What reactants of ATP must be available in the cell in order to produce ATP? O2 d. Brainstorm several cellular processes for which energy or ATP is necessary. Oxidization Glucose‚ or any carbon-based molecule‚ can be burned in oxygen (oxidized) to produce carbon dioxide and water. Combustion reactions

many years‚ people who have been diagnosed with diabetes typically do not live a long life. “Diabetes mellitus is a condition in which the pancreas no longer produces enough insulin or cells stop responding to the insulin that is produced‚ so that glucose in the blood cannot be absorbed into the cells of the body”(Farflex). There have been many advances in the technology of diabetic supplies; this includes the insulin pump. “Insulin pumps are a medical device used for the administration of insulin

Dialysis of starch‚ glucose and sucrose Introduction: Research question: Does the dialysis tube only allow certain substances to pass through the pores because of their size? Dependent and Independent variables: Independent variables: The temperature of the classroom The size of the molecules The size of the pores in the tube The concentration of the indicators Dependent variables: The substance will either pass the pores of the tube or not The result will vary in darkness (color) Controlled

order to determine the effect of the substrate on the rate of respiration of yeast‚ Durham test tube method was used in the first experiment. In this method two test tubes was obtain‚ where test tube one contains distilled H20 with the 7 ml substrate glucose while test tube two contains distilled H20 and with the cofactor in the form of Magnesium sulphate MgSO4. Both tubes has 7 ml 10% yeast suspension. The height of the area filled with gas was measured‚ after thirty minutes the test tube containing

interactions with the hydrocarbon chains of lipids. Alternatively‚ the Brown Bag test can also be used to identify lipids due to the oily nature of hydrocarbon chains. Carbohydrates: Reducing sugars and starches Reducing Sugars Some sugars such as glucose are called reducing sugars because they are capable of transferring hydrogens (electrons) to

monosaccharide is glucose with n = 6. In this way the equation for glucose would be 6 or C6H12O6. . Other basic monosaccharides are fructose and galactose. These three particles have the same atomic recipe. Essentially‚ the course of action of the particles in each of these atoms is somewhat diverse. So albeit each of the three particles are fundamentally the same‚ they are distinctive and unmistakable. Atoms that have the same sub-atomic equation however diverse structures are known as isomers. Glucose‚ fructose
