The first reaction in glycolysis is therefore a phosphorylation of glucose to glucose 6-phosphate. In E. coli this is generally performed by the glucose specific phosphotransferase system (PTS) . This system consists of several enzymes that use phosphoenolpyruvate (PEP) produced during glycolysis as the phosphate source. The products of the reaction are glucose 6-phosphate and pyruvate (PYR). The phosphorylated glucose is converted further to fructose 6-phosphate by phosphoglucose isomerase .
We can achieve a successful oxidation by boiling gently under reflux with acidified sodium dichromate. The fourth practical is to distillate ethanoic acid solution; this is the continuation of the third practical and involves distilling the mixture to obtain a reasonably pure sample of ethanoic acid. The final practical is the filtration of ethanoic acid solution; this involves determining the actual % yield of ethanoic acid by titration against 0.05 M sodium hydroxide. Practical one Equation yeast will carry out anaerobic respiration, using the glucose to enable it to grow and multiply. The equation above shows what the yeast will accomplish inside the bioreactor.
In order to make yogurt, bacteria called Lactobacillus bulgaricus and Streptococcus thermophilus produce lactic acid in the milk culture, which causes the pH to decrease and makes the environment acidic. Ethanol fermentation uses yeast to break pyruvate into acetaldehyde, which makes carbon dioxide. Through the oxidation of NADH glucose becomes ethanol and carbon dioxide. Just like Lactic acid fermentation, Alcohol fermentation utilizes a molecule of glucose that goes though glycolysis and produces two molecules of pyruvic acid and two molecules of ATP. The two molecules of pyruvic acid are converted into two molecules of acetaldehyde and two molecules of CO2.
Trimyristin was then processed to produce glycerol and sodium myristate using sodium hydroxide, ethanol, and water as reagents. After, hydrogen chloride and water were applied to convert sodium myristate to myristic acid via hydrolysis. In terms of reagents and product’s character, sodium myristate has the yellowish look in polar solutions like water because it is lipids that congregate into small droplet called a micelle. Thus, the nonpolar sides congregate on the inside of the micelle and polar ionic ends at the outside surface of the globule. The nonpolar inside dissolves the grease molecules and the ionic outside is washed away.
