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.
