What was the purpose of pontoons #1 and #2? What makes them important? Since they are the controls and the controls must be willing to provide a well-known standard against which almost all comparisons must be made. Confident controls each of the required chemicals are included and negative a negative end result is expected validating the experiment.
What effect did pH level have within the enzyme?
It partially allowed the enzyme to do its job simply because there were positive signs of both starch as well as its reducing sugars.
What result did cooking food and freezing have for the activity of amylase? Boiling did not allow the breakdown of starch because the decreased sugars weren't present and the starch was where the freezing showed a ++ to get the reducing sugars and a negative make starch demonstrating that it reduced the starch.
Activity a couple of
What was the result of the chemical peptidase? Why?
The enzyme peptidase cannot break down the starch by showing there is positive IKI test for starch and a negative Benedict test due to its reduced all kinds of sugar. What is cellulose? According on your results, will salivary amylase digest cellulose? Cellulose can be described as polysaccharide seen in plants to supply rigidity for their cell wall surfaces and salivary amylase is not able to digest this because there were no positive signs of the Benedict check which should have already been positive if a breakdown did occur.
What happened to the cellulose in tube #6?
It had been digested by the bacteria displaying a very confident sign intended for the Benedict test. Activity 3
