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

    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.…

We used what we knew about diffusion to make predictions on what we thought the mass of the dialysis tubing to be after submerging them for 30 mins and we knew that diffuse occurs from highest concentration to lowest concentration.…

    Method: To complete this task, we will first soak our potato cells in different concentrations of sugar solutions. Before we actually soak them, we will need to know the initial mass of the potato cores. After soaking, we will need to know the mass of the final core. We will use the data we collect to find the percent change in mass of the cores…

    The experiment begins by softening up the dialysis tubes by soaking them in a beaker of water. When softened, rub the dialysis tubes between your fingers to reveal the opening and clamp the opposite end. Add 10 mL of the appropriate solution to each bag, squeezing the air out of the tube to make sure there are no air bubbles when clamping the other end of the tube. Three of these bags will be filled with 20%, 40% and 60% sucrose solutions. The other two will contain water. Weigh each bag on a balance after clamping and record initial weight. Fill each beaker with the appropriate solution, just enough to cover the bag; four will have water and the fifth beaker will hold 40% sucrose. The bags containing 20%, 40% and 60% will be placed in water, as well as one bag filled with water; the bag of water in water will act as your control. The other bag of water will be placed in the beaker containing 40% sucrose solution. Place the five bags in their rightful beaker simultaneously and record the time. Every ten minutes the bags should be removed, blotted to get the excess solution off and then weighed. Continue weighing the bags every ten minutes for ninety…

    Exercise 1B: First, soak six 30-cm of dialysis tubing in water. Then, take each one out and tie a knot on one end of each piece to make a bag. Pour 25 mL of a different solution (distilled water, 0.2 M sucrose, 0.4 M sucrose, 0.6 M sucrose, 0.8 M sucrose, and 1.0 M sucrose) into separate bags. Tie the other end of the bag, leaving sufficient space for expansion. Record the initial mass for each bag in grams. Then, fill the cups with distilled water. Place each bag in one cup and label each cup with each solution. After 30 minutes, remove the bags from the water. Finally, record each bag…

    Starch Lab Report

    Since the glucose went from a higher concentration to a lower concentration, that is why the molecular transport was diffusion. The passive transport gave us a larger amount of glucose in the solute and a smaller amount in the solvent. Osmosis also occurred, because the water molecules were able to get past the permeable membrane giving us a larger volume in the dialysis bag, then what we started…

    In the wake of pushing potato center out from center barer, we needed to cut potato center into two equivalent amounts of. Thereafter, we quantified each center with a plastic ruler by millimeters, recording the length and the measurement of each. Furthermore, we needed to feel the potato centers and clarify how they felt before placing them into two unique sorts of an answer so we would have the capacity to find the progressions. Every half at that point set into two separate holders with one loaded with a salt arrangement and the other with refined water. An import detail what we need to recall was to cover the potato centers completely with their answer, else, we wouldn't have the capacity to get right outcomes.…

    The Effect of Solute Concentration on Osmosis in Potatoes.

    Take a potato and cut out 10 cubes using a scalpel, which are equal in size. After, 10 test tubes have to be selected for a different sugar solution concentration each, starting from 0.1 mol/l until 1.0 mol/l. First make a solution of 1mol/l using powdered sucrose (the mass needed to do so can be found using the formula n=m/M and weighed with a balance. Place the solutions into test tubes and fill with distilled water until the total volume of solute on in each test tube…

    Biology lab report diffusion

    For part A of the experiment, the following items are needed: Dialysis tubing, IKI solution, 15% glucose/1% starch solution, distilled water, balance, sucrose solutions (0.2M, 0.4M, 0.6M, 0.8M, 1.0M), glucose test tape, beakers (multiple), petri dish. In the experiment, one will measure diffusion through a selectively permeable membrane (dialysis tubing). A 30 cm by 2.5 cm piece of dialysis tubing that has been soaked in water is acquired and made into a bag by tying one end of the dialysis tubing and opening the other end. Next, place 15 mL of the 15% glucose/1% starch solution into the dialysis tubing. After this step, tie off the end that is still open and effectively turn it into a model of a cell (for the purpose of this lab). Afterward, fill a beaker with 250 mL of distilled water but bake sure that the beaker is either three-fourths full. 4 mL of IKI should be added to the beaker and the color should be recorded. In order to check for contamination, perform the Benedict’s test on the water and measure with glucose tape. Next, in order to place the dialysis tubing into the beaker, rinse the tubing with distilled water and make sure that there are no leaks or tears in the bag. Slowly place the bag into the beaker and make sure the tubing is completely submerged. Allow the bag to stay in the water for 30 minutes unless a color change is observed in the bag or the beaker. Finally, test the liquid in…

    We soaked several discs of potato cuted using a cork borer with around 1 centimeter of diameter and 2 milimeters of lenght into sucrose solutions with a different range of concentrations from 0 to 1.0M. Then we weighed all the potato cylinders on an electronic balance (see results) and recorded the results. We placed enough pieces of potato to cover the bottom of the petri dish and left them for 60 minutes. After this time we drained out the solutions from the petri dishes and carefully placed them in order of molarity on a paper towel.…
