  • What Is The Potato Content Of A Potato Experiment

    labeled accordingly to the sucrose solution molarity. Each beaker received 100-mL of the various solutions. However one beaker received 100 mL of Deionized water with a molarity of 0.0. Afterwards a cork borer was pushed through the potato and was twisted back and forth. Once the borer was filled it was removed from the potato. Pushing the potato cylinder out of the borer, this this step was repeated six more times in order to get seven undamaged potato cylinders. Using a sharp razor blade, the potato cylinders were both cut to a uniform length of about 5cm, and were removed of their potato skins. The potato pieces were also cut in half to give the cells a greater surface area in which it was easier to absorb the solution. After the cylinders were weighed on a balance and the data was recorded in Table 4. Using the razor blade each potato was cut lengthwise into two long halves. Then the potato pieces were transferred to the water beaker and the time they were submerged was recorded. This step was repeated for all potato cylinders in which the pieces were placed in solutions 0.1 to 0.6 M. The potatoes were incubated for ninety minutes. At the end of the incubation period the time was recorded. Then the potato piece was removed form the first sample. Next potato pieces were weighed the and the final weight was recorded in Table 4. This procedure was repeated until all samples had been weighed and recorded in the chronological order they were initially placed in the test…

  • Potato Enzyme Experiment

    Abstract: In this lab, three variables were tested to discover their effect on the enzyme catalase, taken from a cut and blended potato. The blended potato mixture was strained and put into a centrifuge, the liquid that was in the centrifuge contained the enzyme and remained on ice. The enzyme was placed in test tubes that had varying levels of pH buffers, substrate concentrations and temperatures; the pH, substrate concentration and temperature were the three variables. The data showed that…

  • Potato Cell Experiment Essay

    Furthermore, analysis of the results allows the approximate salt concentration of the potato cells. The least mass change suggests the internal cell environment is isotonic to the external cell environment. Using the logarithmic trend line (which has an R2 value of 1), it demonstrates that the lowest mass changes…

  • Osmosis Experiment Essay

    On the day of this experiment, it was reasonably warm, suggesting that due to the higher the temperature, the faster osmosis occurred. This would similarly occur during cooler conditions, however with the opposite effect of a slower osmosis rate. When there is a higher temperature the amount of energy present in the water increases causing the faster effect. It could be assumed that the solution used in each beaker was at the same temperature. The solution came from the same bottle found in the…

  • Potato Osmosis Lab

    The materials needed are three small beakers (150 or 250 mL), a potato, a knife to cut the potato, a ruler to measure the potato, something to weigh the potato pieces, a timer, and three solutions: distilled water, 10% sucrose, and 50% sucrose. The point of this experiment is to calculate the percent change in the mass before and after soaking the potato in the three different solution. Create your own hypothesis before beginning the experiment. My hypothesis is that the potato soaked in water…

  • Potato Enzyme Lab Report

    Activity of Enzymes within a Potato Independent Variable: Temperature Dependent Variable: Visible amount of Fizz Constant: Size of Potato being used Introduction We have studied information about chemical reactions and how a catalyst is used to speed up reactions. We have learned that enzymes (proteins) in eukaryotic cells work as a catalyst to make this possible. Each enzyme in a eukaryotic cells has specific molecules it binds to, as they have a specific frame work. This…

  • Potato Osmosis Lab Report

    The correlation portrays that as the concentration of the solution increases, the mass of the potato decreases. As the potato was placed into the solution the mass of the potatoes increased. The increasing of mass means that the volume of water inside the potato would have increased .this is all due to osmosis. The water particles from inside the potato diffused to come into the concentrated sodium chloride. These results prove that my prediction is correct. However you notice that there is a…

  • Potato Osmosis In Potato

    This decrease in mass can be explained by exosmosis, where water leaves the cells of the potato due to there being lower water potential in the sucrose solution than the potato cells. (see Fig 2). For 0.3M the average percentage change in mass was -0.88%. This then decreased as the concentration of sucrose increased, with 1.0M having an average percentage change of -30.48%. This decrease in the average percentage change is mass is due to the fact that as the concentration of sucrose solution…

    they cause the reactions to occur faster without changing themselves. For this experiment the substrate in the enzymatic reaction was sucrase, and it will be causing sucrose to change resulting in the following equation: Sucrose → Glucose + Fructose Where the arrow is in the equation indicates the enzyme sucrase to speed up the reaction. In the experiment conducted we were looking for the effect of a cofactor that could have impacted enzyme activity. A cofactor is required for enzymes to…

  • Quantification Of Fats From Food Essay

    substance in the petri dishes on day 2 was recorded. Results In this experiment, lipids were extracted from chocolate chips, potato chips, and sunflower seeds, first by heating and then by chemical extraction. The results of the heating process are listed in Figure (A). The samples left behind grease marks where the oil had began to rise and made contact with the paper towel from the surface of the food. In the second experiment acetone was used to extract the lipids. It left behind only the…
