insert into cuvettes‚ a micropipette was then used to obtain 0.5ml of catechol and 0.5ml of the catechol oxidase. The pH buffer was made first to avoid any denaturation of the catechol oxidase. Our positive control for this experiment was pH 7 because that is the pH level of most cell membranes in the cytoplasm (Whitson‚ 2016.) Our negative controls varied for each pH buffer‚ but all “blank” cuvettes contained 0.5 ml of catechol oxidase and 4.5ml of the pH buffer. We prepared the negative control for

The Philippine banana industry is one of the top agricultural export earners. The increase in demand worldwide has resulted to greater expansion of area planted to banana. As a tropical country‚ Philippines grows an abundant varirety of fruit crops primarily for local consumption and export market. Banana is considered as the most important fruit crop in the country in terms of volume production and export earnings. Philippines ranks second to Ecuador as the top banana-exporting country in the world

Week 11 Theme: Health What Are the Benefits of Eating Banana Peels? Bananas have been a highly cultivated fruit for thousands of years. Many species of primate consume the entire banana‚ peel and all‚ which may have led indigenous peoples to follow suit. Although not common practice in the West‚ peoples of Asian countries eat banana peels‚ but they are usually cooked in some capacity. They are not nearly as sweet as the flesh‚ but they are rich in some nutrients‚ especially potassium‚ and

Within the banana supply chain‚ plastic bags are utilized since the very in many stages for example at the packaging station‚ the bananas will be packed into cardboard boxes with an inlay of a plastic bag or at the wholesalers‚ three to five bananas will be wrapped in one plastic bag and the customer at the retailers will buy all those amounts. It is all known that after bananas are consumed‚ plastic bags will become wasted. There are already

Bananas are the fruit of a plant of the genus Musa‚ which are cultivated primarily for food‚ and secondarily for the production of fibers. It is alleged that there are almost 1000 varieties of bananas in the world‚ subdivided in 50 groups (Bora‚ 2007). The most generally known banana is the seedless Cavendish variety‚ which is the one produced for export markets and pronounced for consuming. The banana is the fruit of an herbaceous plant related to the orchid family and is most commonly found in

Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

to the following direction. 4. Continue your work area and add 1cm of potato extract obtaining catechol oxidase to each of the seven tubes. 5. Add 1% catechol to each of the 7 test tubes‚ bringing the total volume to the 6c mark. Agitate the contents of the tubes using a vortex mixer if available. 6. At time 0‚ record the relative color intensity of each tube immediately after adding the 1% catechol. 7. Place the tubes in 40’C water bath. 8. Agitate the tubes periodically over the next ten minutes

Lab Ex#8: "Enzymes: Catalysts of Life" INTRODUCTION Enzymes are protein organelles where chemical reactions take place to generate energy within our cells. Without the energy produced from the cell enzyme activity‚ we would not possess the catalyst activity necessary for energy to produce movement. Each enzyme performs a specific function within our bodies. Those functions performed can be significantly altered with the introduction of variables outside their environment. Variables‚ such as temperature
