Question

What procedure did you follow to understand anaerobic respiration in your school laboratory?

Answer 1

Take some fruit juice or sugar solution and add some yeast to this. Take this mixture in a test tube fitted with a one-holed cork.

Fit the cork with a bent glass tube. Dip the free end of the glass

tube into a test tube containing freshly prepared lime water.

The lime water turns milky as carbon dioxide released by yeast due to fermentation reacts with the lime water.
