23. Investigation into factors affecting respiration in yeast
- 00:54 Why is sucrose solution added to the yeast suspension?
- 01:12 Why must the syringe have a weight on top?
- 01:25 What gas is given off?
- 01:30 How could you improve the precision of this experiment?
yeast suspension (100g/dm3)
Sucrose solution (0.4moldm-3)
access to hot and cold water
1dm3 beaker for carrying water
Yeast solution - irritant to eyes
Contact with eyes
Eye: flood with tap water (10min)
