pyruvate splits itself into carbon dioxide and acetaldehyde. NADH is then taken from the acetaldehyde and ethanol is left. (Starr‚ Evers & Starr‚ 2011) Bread making is an example of alcoholic fermentation‚ the yeast being the reason that the bread rising. As explained before the carbon dioxide molecules that are given off during the second stage of fermentation caused the dough to rise and the ethanol that was left bakes out of the bread. Methods and Materials In order to start this experiment

My hypothesis for this experiment is that the greater the concentration of glucose will be added‚ the faster the rate of respiration will be. This is because more glucose added to the yeast will mean more glucose to break down‚ therefore producing ethanol and carbon dioxide. Also to support my hypothesis I would mention that‚ more concentration of glucose will result in the more heat energy produced and so more molecules will move around and collide. Anaerobic Respiration equation: GLUCOSE →

production of acetone and butanol by means of solvent-producing strains of Clostridium spp. was one of the first large-scale industrial fermentation processes to be developed‚and during the first part of this century it ranked second in importance only to ethanol fermentation. The reason for the almost total demise of this fermentation in the early 1960s was the inability of the fermentation process to compete economically with the chemical synthesis of solvents. However‚ interest in the use of renewable resources

The methylene blue staining procedure is used to measure yeast viability based on the assumption that the methylene blue will enter the cells and be broken down by living yeast cells that produce the enzymes which breaks down methylene blue‚ leaving the cells colourless. The non- viable cells do not produce this enzyme (or enzymes) and as such the methylene blue that enters the cells are undegraded causing the cells to remain coloured (the oxidized form concentrates intracellularly). The coloured

#15 Synthesis of Ethyl Salicylate from Salicylic Acid ____________________________________________________________ _______________ Purpose: Salicylic acid is converted to the liquid ethyl salicylate by addition of ethanol. Yields of salicylic acid (week 1) and ethyl salicylate will be found‚ as well as the overall yield of the 2-step conversion of acetyl salicylic acid to ethyl salicylate. Introduction: Esters are formed from the reaction of acids and alcohols: O O

ALAK Many cultures use alcohol or “ALAK” in Philippines as a social lubricant and a way to relax. People also drink alcohol because of peer or media pressure‚ to cope with stress or other problems or because of genetic factors. The ethyl alcohol‚ or ethanol‚ in alcoholic drinks such as beer‚ wine and liquor is a central nervous depressant‚ which has short-term and long-term effects on the body. People drink for different reasons. For example‚ adolescents may drink because of peer pressure‚ to cope with

D4 H and E staining procedures Haematoxylin and eosin staining is a technique used by pathologists to add definition to nuclei and other parts of a cell in tissue samples under a microscope so that they can see it better when analysing the cells form and abnormalities. The H&E technique is the most commonly used in histology and the diagnoses of malignancies is based largely on the results of this procedure. The dyes will specifically stain elements of a cell or tissue because the dyes have a high
