What happens when yeast is added to any dough?

Explanation

When yeast is added to any dough, the following steps occur:

1. **Presence of Sugar**: The dough contains sugar, which is essential for the yeast to function. Yeast is a type of fungus that requires sugar to carry out its metabolic processes.

2. **Fermentation Process**: When yeast is added to the dough, it begins to ferment the sugar present in the dough. Fermentation is a process where yeast converts sugar into alcohol and carbon dioxide (CO2) under anaerobic conditions (without oxygen).

3. **Production of Carbon Dioxide**: As the yeast ferments the sugar, it produces carbon dioxide gas. This gas is crucial because it creates bubbles in the dough.
