Potato

Problem: The research questions being examined in this investigation is, How can we generate electricity by using Potatoes to light an electric bulb? Background Information: How does a potato battery work? The copper (Cu) particles pull in electrons more than the zinc (Zn) molecules. On the off chance that you put a portion of copper and a piece of zinc in contact with each other, numerous electrons go from the zinc to the copper. As they focus on the copper, the electrons repulse each other.…

The Great Grandparents on Dad’s Mother’s side immigrated from Ireland during the Great Potato Famine when they were 18 and 19 years old. This was a time of tremendous hardship for many people in Ireland as the main agricultural crop; the potato failed badly for a number of years in a row. People in Ireland were found dead with green rings around their mouths as they ate grass in a vain effort to survive. Mothers and Fathers placed their faith and children on boats to America in an effort to…

Cellular Death: Tonicity on Potato Cells Introduction The purpose of this experiment was to test the effects of tonicity on potato cells. During this experiment slices of a potato were placed into beakers containing salt solutions with different concentrations. How will the percentage of salt concentration in solution affect a plant cells water content? This experiment will determine which salt solution concentrate will cause the potato cells to absorb water or lose water. Tonicity in…

sucrose concentration where the mass of 2cm^3 of Classic Russet potato segments and pear segments does not change, representing an isotonic concentration. By calculating the change of mass of the potato segment and pear segments prior to being placed in the sucrose solution against the mass after being in the sucrose solution for 45 minutes. Our goal was to determine what type of osmotic concentration was created as compared to the potato and pear segments. The results of the lab indicated six…

molecules lay outside of the potato, while the saltwater was naturally hypotonic because of the higher concentration in it. The Tap Water solution, however was the oddball of the three, Tap water is dependent on the location and quality of your water meaning it could've been hypotonic or hypertonic. In this experiment the potato was used to model a cell experiencing osmosis, like a cell, the potato will let really small particles inside of it but without manipulation the potato will not let…

hypothesis. Catalase concentration: Upon adding the potato pieces to the test tubes while waiting to measure the production of O2, we noticed right away that tube A is not doing anything because its only contains hydrogen peroxide and not any enzyme catalase to start the reaction while tube B, which contained 1cm potato piece produced 7.7cm fizzing, tube C, which contained 2cm potato piece produced 8.5cm fizzing and tube C, that contained 4cm potato piece had a greater amount of O2 (11.5cm) in…

Explain the results you obtained using a piece of muscle and a piece of potato?. Both the test tubes will show decomposition of hydrogen peroxide because both potato and uncooked ham have catalase enzymes. 5. What effect did acetic acid (vinegar) have on the reaction? Why? The catalase enzyme works best at pH 7 but it can perform well between 6.8 to 7.5. A 0.1 M Vinegar…

for each substance tested which indicated that they all contained catalase. The potato had the highest reaction rate which indicates it contained the highest amount of catalase while the chicken contained the second most and the apple contained the least. Catalase is involved with photorespiration which is a process that lowers the amount of water and light absorbed from making hydrogen peroxide which is why the potato contained a higher concentration of catalase. When looking at the effects of…

The minds of millennials are to companies what the universe is to the rest of the world; forever changing and impossible to understand. It is no secret that many companies have taken to social media in an attempt to gain the attention of the younger generations and it is equally evident that many of these attempts have failed. Companies start campaigns geared towards millennials in the hope that it will gain their attention. For companies like Lays and McDonalds, they not only failed to…

)During the lab and based on recorded observations it can be deduced that the enzyme catalase found in potatoes only reacted to hydrogen peroxide. This is do to the fact that before 10 ml of hydrogen peroxide was added to each test tube residing 3 potato samples and the designated liquid, no reaction was observed. Thus demonstrating the catalase's inability to react to vinegar, soda, water, detergent, and Na OH. Furthermore, shortly after the hydrogen peroxide was added to the liquids of…
