What to Include in Your Lab Write–Up
Lab: Enzyme Amylase Action on Starch

Introduction:

  • What is an enzyme
  • Describe an enzyme’s structure
  • Explain how an enzyme works (substrate, active site)
  • What’s amylase
  • Where is amylase found
  • What denatures amylase (proteins)
  • Describe the Benedict’s test

Hypothesis:
Exposure to heat or extreme pH will …

Materials:
The materials used include…

 Methods:
Type the procedure in paragraph form.

Results:

Complete this table

Test Tube Contents of Tube Color of Tube After Heating + or – Benedict’s test Enzyme Denatured

Yes or no

A Starch + Saliva + Vinegar
B (Starch + Saliva) Heated
C Starch + Saliva

 Conclusion:

  • Restate the hypothesis
  • Explain the results of the Benedict’s test on Tube C (color change, contents of tube, NOT heated)
  • Explain the results of the Benedict’s test on Tube A ( color change, contents on tube, what was added before heating)
  • Explain the results of the Benedict’s test on Tube B ( color change, contents on tube, heating tube)
  • Tell what denaturing proteins is & how did the Benedict’s test show this.
