Yeast is the unicellular plant, it will go for an anaerobic respiration and will release CO2 and as you have written there are also sugar and water. these all conditions are in favour in respiration that's why bubbles will be formed. i hope you are satisfied with my answer.

Respiration:
The formation of bubbles in the mixture of yeast, sugar, and water observed after one hour is due to respiration taking place in the yeast cells. Yeast is a single-celled fungus that undergoes anaerobic respiration, also known as fermentation, in the absence of oxygen.
Yeast Respiration:
- Yeast cells break down sugar (glucose) through a series of enzymatic reactions to produce energy in the form of ATP.
- During this process, carbon dioxide gas and ethanol are released as byproducts.
- The release of carbon dioxide gas leads to the formation of bubbles in the mixture, which is a visible indication of the respiration process in yeast.
Importance of Respiration in Yeast:
- Respiration in yeast is essential for its survival and growth as it provides the necessary energy for cellular functions.
- The production of carbon dioxide gas and ethanol through respiration also has industrial applications, such as in the fermentation of alcoholic beverages and bread-making.
Conclusion:
In conclusion, the formation of bubbles in the mixture of yeast, sugar, and water is a result of the respiration process in yeast cells, where sugar is broken down to produce energy, carbon dioxide, and ethanol. This phenomenon demonstrates the metabolic activity of yeast cells and their ability to carry out anaerobic respiration in the absence of oxygen.
