“Beano™ and Lactaid™ Action”
|
| Rationale: |
- To show the action of two different commercially prepared enzymes, Beano™ and Lactaid™.
|
| Time: |
- Approximately 30-40 minutes for 1 trial
|
| Objectives: |
- To test the action of two commercial products, Beano™ and Lactaid™
- To use glucose test paper to monitor the presence of glucose
- To determine if yeast can metabolize glucose, lactose, or galactose
- To determine if yeast can metabolize glucose, lactose, or galactose in the presence of Beano™ or Lactaid™
|
| Materials: |
- CBL/TI system
- Vernier Gas Pressure Sensor
- glucose test paper
- 5% sugar solutions
- yeast suspension
- see lab for other materials
|
| Overview: |
- Students will monitor CO2 production for evidence of fermentation in yeast with and without the help of commercial enzymes.
