When we put the Lugol’s trustee ( I2Kl ) in the beaker, we can detect the effects of osmosis as the Lugol’s trustee ( I2Kl ) solution on the exterior of the beaker permeates the bowel ( Dialysis tubing ) bring oning a chemical reaction that will turn the liquid in the bowel ( Dialysis tubing ) blue-black.
If the amylase successfully digests the amylum, what consequences would you anticipate? If the amylase successfully digests the amylum, I would anticipate a no colour alteration occur every bit good as a presence of glucose in the bowel ( Dialysis tubing ) .
If the amylase merely partially digests the amylum, what would you anticipate to go on? If the amylase merely partially digests the amylum, I would anticipate to see a swoon colour alteration every bit good as a little presence of glucose inside the bowel.
If the amylase fails to digest the amylum, what consequences would you anticipate? If the amylase fails to digest the amylum, I would anticipate the solution inside the bowel ( Dialysis tubing ) to alter colour to blue-black due to the chemical action that will happen when the Lugol’s trustee ( I2Kl ) permeates through the bowel ( Dialysis tubing ) .
Why is it necessary to hold a control for this experiment?
By holding a control in this experiment, we can see the alterations with the presence of amylase. Lugol’s trustee ( I2Kl ) changes colour in the presence of amylum, which is the control group that we have setup that demonstrates what would go on of course, with amylum and Lugol’s trustee ( I2Kl ) . The control group will hold a distinguishable comparing available for us. As amylase, an enzyme that catalyzes the dislocation of the amylum into glucose, which will hold no reaction with Lugol’s trustee ( I2Kl ) every bit good as no colour alteration.
Were starch molecules able to traverse the membrane?
No, the amylum molecules were non able to traverse the membrane, because if it were able to go through through, so the solution on the exterior of the bowel ( Dialysis tubing ) would hold changed colour to blue-black.
Were Lugol molecules able to traverse the membrane?
Yes, the amylum molecules were able to traverse the membrane as we observe the colour changes that occur inside the bowel ( Dialysis tubing ) .
What is your decision respect amylase digestive activity?
In this experiment, I concluded that amylase have the abilities to catalyse the dislocation of the amylum into glucose. Besides, some molecules, such as the Lugol’s trustee ( I2Kl ) and glucose are able to pervade through bowel ( Dialysis tubing ) while others, such as amylum is non able to pervade through the ( Dialysis tubing ) .
What does this experiment state you about the size of glucose molecules and membrane permeableness? This experiment tells me the size of the glucose molecule is really little in comparing to starch molecule. They have high membrane permeableness that allows them to pervade through the bowel ( Dialysis tubing ) ; this is supported by the presence of glucose in the H2O when we conducted the glucose trial.
In the experiment, did the motion of glucose and amylum molecule reflect the expected consequences of biological simulation?
In this experiment, the glucose and amylum molecules accurately reflected the expected consequences of the biological simulation. Animal’s amylum molecule can’t cross the plasma membrane to go forth the bowel, similarity in our experiment, the amylum solution were non able to pervade through the bowel ( Dialysis tubing ) , therefore a no alteration of colour occurred in the Lugol’s trustee ( I2Kl ) solution. Furthermore, the glucose molecules can traverse membrane between the bowel and circulatory system, and this is proved accurate as we were able to prove the presence of glucose in the Lugol’s trustee ( I2Kl ) solution that contain amylase in the bowel
( Dialysis tubing ) .
