Respiration in living yeast cells
We will observe the progress of glucose metabolism in living yeast cells using an indicator, methylene blue. This material is blue in the presence of oxygen and clear when no oxygen remains. Procedure:
1. Obtain a test tube -10ml
2. Fill it 3/4 full with equal portions of yeast suspension (3ml) and glucose solution (3ml).
3. Add one drop of methylene blue solution. Shake tube to mix, convering opening with parafilm.
4. Place into rack and observe
Will holding the tube in your hand speed up the reaction?
Yeast is a single-celled microorganism. Yeast is a member of the kingdom Fungi. Living yeast cells breakdown the glucose in the presence of oxygen via aerobic respiration to form carbon dioxide, water and energy.
Answer and Explanation:
Yes, holding the test tube in the hands speed up the reaction.
Any cell lives in the optimum conditions of pH, temperature and...
