Jacob And Glucose Lab Report
Procedure
Diffusion
Jaydon, Jacob and Tyler obtained a 30 cm piece of dialysis tubing and cut 2.5cm off of the 30cm piece and soaked it in water. Then they tied one side off to form a bag. They then rubbed the other end of the bag to open it up and then are able to fill the bag with solution. The next step of the lab was to test for the presence of glucose in a 15% glucose and 1% starch. Then they took the 15% glucose and 1% starch and took 15 mL and placed them in enclosed bags. Jaydon, Jacob and Tyler then tie off the bag leaving room for expandable contents in the solution.
Then they took distilled water and filled it with 250 mL beaker or one other option includes filling a cup up ⅔’s of the way full with the distilled water. Then they took the distilled water and added about 4 mL of Lugol’s solution. Then they put the bag in the beaker solution.
Then watch for any odd things to happen like change of color in bag or beaker. They let it stand for a good 30 minutes. Then they recorded what happened. Jaydon, Jacob and …show more content…
They then sliced potatoes approximately 3 cm thick. To cut the potatoes Jaydon, Jacob and Tyler used a cork borer, do not include any skin of the potato in this process. Jaydon, Jacob and Tyler used 4 cylinders of the potato. Jaydon, Jacob and Tyler covered there potato slices til it was their turn to use the balance. Then they determined the mass of the 4 cylinders together and recorded the mass. Jaydon, Jacob and Tyler took the sucrose solution and inputted is with the potatoes. Jaydon, Jacob and Tyler covered the beakers with plastic wrap to prevent evaporation. Then they let the potatoes stand overnight in the sucrose solution. Jaydon, Jacob and Tyler then removed the covers from the beakers the next day. Jaydon, Jacob and Tyler put the potatoes gently on paper towels and determined there mass. Jaydon, Jacob and Tyler then recorded all the data on their

    Fill 4 dialysis tubes 2/3 of the way with 1 M glucose solution. Fill 4 beakers with 100 mL of 1 M sucrose. Weigh all four bags before placing them into beakers. Record temperature of room temperature sucrose and place one bag into that beaker for ten minutes. After ten minutes, take the bag out, dry, and weigh. Heat up two beakers of sucrose solution to two different temperatures, record the temperatures, and place the bags in for ten minutes. After ten minutes, take the bags out, dry, and weigh. Cool down one beaker full of sucrose with ice, record the temperature, and place the last bag into the beaker. After ten minutes, take the bag out, dry, and weigh.…

    Diffusion Through Membranes Lab Report

    Measure and pour 50 mL of water into a 100 mL beaker. Cut a piece of dialysis tubing 15.0 cm long. Submerge the dialysis tubing in the water for at least 10 minutes. I measured and poured 82 mL water into a second 100 mL beaker. While the dialysis bag was soaking, made the glucose/sucrose mixture. Using a graduated pipette to add five mL of glucose solution to a third beaker and labeled it “Dialysis bag solution”. Used a different graduated pipette to add five mL of starch solution to the same beaker. Mixing and pipetting the solution up and down the pipette six times. Used the same pipette that I used to mix the dialysis bag solution, removing two mL of that solution and placed it in a clean beaker. That sample served as my positive control for glucose and starch. Dipped one of the glucose test strips into the two mL of glucose/starch solution in the third beaker. After one minute had passed, recorded the final color of the glucose test strip. Used a pipette to transfer approximately 0.5 mL of IKI to into the two mL of glucose/starch solution in the third beaker. After one minute had passed, recorded the final color of the glucose/starch solution. I used a clean pipette, and removed two mL of water from the 82 mL of water and placed it in a clean beaker. I dipped one of the glucose test strips into the two mL of water in the beaker. After one minute had passed, recording the final color of the glucose test strip. Used a pipette to transfer approximately 0.5 mL of IKI to into the two mL of water in the beaker.

    We tied one end of the glucose tubing, and put 2 inches of glucose solution into it then we tied the other side into a knot to close it up. With the second dialysis tube we did the same thing but with the starch solution. We then weighed the glucose cell, then the starch cell, and recorded the mass into the chart. After that we placed each cell into a seperate cup, and filled it with water. We let the cells sit in the cups overnight. The next day we got our cup with the glucose cell, we took a glucose test strip and dipped it into the water in the cup to test for glucose. Then we took the cell out of the water, weighed it, and recorded it in the chart. We took the cup with the starch cell and tested it for starch by using lugols iodine. We put 4 drops of the iodine into the cup. We took the starch cell and weighed it, then recorded…

    Fermentation of Yeast with Carbohydrates

    The diffusion of glucose, starch, and iodine was observed when the solutes went from a higher concentration of their individual solute to a lower concentration diffusing threw pores in the dialysis bag. The experiment sought to find out which solutes would diffuse threw the pores of the dialysis bag, whether in or out of the bag. The pores and walls of the dialysis bag acted as a permeable membrane, like the one found in cells, and was the regulator of diffusion for the solutes. Studying the movement of solutes threw the dialysis bag helps better understand diffusion of a cell membrane, and the means and solutes that make a solution isotonic. If the iodine concentration is higher outside the dialysis bag of starch and glucose than in it, iodine along with water will diffuse into the bag while the starch remains in the dialysis bag and some glucose will diffuse out of the dialysis bag.…

    In this exercise, we tested diffusion through dialysis tubing. This was done through a demo with the teacher, rather than individually in groups. First, a piece of 2.5cm dialysis tubing was obtained. Then one end was folded and clipped securely so that a solution poured into the bag would not leak out. Next, the other side of the bag was opened. For step two, a 15% glucose/1% starch solution was tested for the presence of glucose with Benedict’s, and we recorded the data in a table. Using more 15% glucose/1% starch solution, 15 mL was placed in the dialysis bag. The other end was tied,…
