j Abstract Enzyme inhibition is important because it helps cure sickness by injecting the correct inhabitant. PTU was experimented to discover what type of inhibitor it is to Catechol Oxidase (Potato Extract) by seeing if there is a color change when the two interact. Results show that PTU was not a competitive inhibitor, saying that it did not bind to the Potato Extract (Catechol Oxidase. Introduction Enzyme inhibition is important in life because many medications contain enzyme inhibitors, some being competitive inhibitors and other noncompetitive. Competitive meaning it would bind to the active site therefore blocking it decreasing enzyme activity, noncompetitive being that it would just simply bind elsewhere and or change the shape of the enzyme causing no feedback.
For the food test that use to determine the of presence protein we use Biuret test instead of Million’s Test. The reason why we are choosing the Biuret test is because the Millon’s Test cannot have positive result on specific protein such as gelatine due to the gelatin had no tyrosine beside the Million’s Test will show positive result on every substance which had the tyrosine including non protein substance. So we used albumin solution and it will only show positive result on protein only. Objective -To determine the presence of reducing sugar by carrying of Benedict’s test -To determine the presence of non reducing sugar by carrying out Hydrolysis process by using dilute hydrochloric acid. -To show the presence of starch by carrying out iodine test.
Biology Unit 6: Investigating tomato inhibitors on the germination of seeds Abstract The aim of this investigation is to investigate the effect of different germination inhibitors of tomato on seeds. A number of tomato seeds from tomatoes of the same variety were extracted and placed in a petri dish with cotton wool. With the use of tomato germination inhibitors like tomato juice, high level of sugar and gel coat, I was able to measure the percentage germination of the seeds. The results obtained showed that the gel coat that is found around each tomato seed and the tomato juice itself act as germination inhibitors resulting to the non-germination of the tomato seeds; agreeing with the experimental hypothesis. The t-test was used to show the statistical significance between the germination inhibitors and germination of seeds.
Per Organic Consumers Association, Irradiation is a ‘magic bullet’ that will enable the company to say that the product was ‘clean’ when it left the packing plant. The claim, more rather, lacks the key source in evidence, for even the best sanitation and standard antibacterial treatments cannot ensure safety in foods. In addition, irradiation cannot occur properly if the food is too heavily contaminated, preventing industries from using this practice as a substitution for good sanitation practices. Irradiation is not harmful in producing resistant strains of bacteria, nor does it make food radioactive. It simply reduces the amounts of bacteria in foods that may become potential illnesses in humans.
Who made the greatest contribution? First of all, Pasteur demonstrated that fermentation is caused by the growth of micro-organisms, and that the emergent growth of bacteria in nutrient broths is not due to spontaneous generation but rather to biogenesis 'all life is from life'. Pasteur was convinced that microbes caused diseases in humans but his work on cholera had failed. He was never able to directly link one microbe with a disease, whereas Koch succeeded in doing this. While Pasteur was not the first to propose germ theory, he developed it and conducted experiments that clearly indicated its correctness and managed to convince most of Europe it was true, although he didn't actually prove it, it just supported the theory.
Introduction: Fermentation of yeast can be used to produce bread and alcoholic beverages. Yeast fermentation is the breakdown of sugars in the absence of oxygen. The proper enzymes need to be capable of breaking the food’s chemicals in a useful way. Yeast is capable of using some, not all sugars as a food source. Yeast can metabolize sugar in two ways, aerobically, with the aid of oxygen or anaerobically without oxygen.
All about Yeast Infection Treatment Women are considered more susceptible to fungal infections, which is a form of yeast infection. Candida albicans is the type of fungus that causes this consequently came to be known as Candida infection. Although there are a variety of medical solutions that can be found in pharmacies and drugstores for its treatment, experts suggest that natural yeast infection treatment would be the best solution so far. It is very rare that this type of infection can have serious consequences, but it can actually prove to be very uncomfortable. vaginal yeast infection While it is true that most of the over the counter yeast infection treatments can provide relief, the results can not actually prove to provide a long-term
Results At the end of the experiment, the number one petri dish that was swabbed and had water ran thru it number one had growth the size of a quarter. The petri dish numbered 1a had the size of a nickel. Petri dish numbered two had a growth the size of a quarter similar to culture number one. The petri dish labeled 2a had fungal growth all over the petri dish. Discussion The result of the experiment determined that water did not spread the fungal spores as well as the low airflow.
Causes and spread of infections 1 Understanding the cause of infection Bacteria can be both beneficial and pathogenic. These single cell micro-organisms are tiny living beings, neither plant or animal, that normally exist together in millions and reproduce only asexually. Some of their common illnesses and infections include ear infections, food poisoning, urinary tract infections, diphtheria, bacterial meningitis, gastritis and sinusitis. Viruses differ from bacteria, being coated genetic material and in that they do not reproduce on food, needing a living host to do so. They replicate by invading targeted cells of their host and taking over genetic material responsible for reproduction.
The insulin that the Islets had been creating was being destroyed by proteolytic enzymes. These enzymes are located all throughout the pancreas, keeping the insulin from ever leaving. He then came to the conclusion that he needed to figure out how to extract the insulin before it was destroyed. In a rare case from 1920, Banting noticed an autopsy that showed that pancreatic stones had blocked the pancreatic duct but the Islets of Langerhans were unaffected. He speculated that if the pancreas was given time to degenerate, the secretion of the Islets of Langerhans could be extracted.
