Yes, the amount of yeast used can affect the amount of foam produced during fermentation. More yeast can lead to increased foam production, especially during the early stages of fermentation when yeast is most active. However, excessive foam can also lead to overflow, so it's important to use the right amount of yeast for the recipe.
When yeast is mixed with warm water and sugar, it activates and begins to ferment. Fermentation produces carbon dioxide gas as a byproduct, which gets trapped in the liquid, creating foam. The foam is a result of the carbon dioxide bubbles rising to the surface of the mixture.
The amount of yeast in the elephant toothpaste experiment affects the rate and volume of foam produced. Yeast acts as a catalyst for the decomposition of hydrogen peroxide into water and oxygen, and a higher concentration of yeast increases the reaction speed, leading to a more vigorous and rapid release of oxygen. This results in a larger amount of foam being generated in a shorter time. Conversely, using less yeast will produce less foam and a slower reaction.
Yeast makes the crust rise.
Yeast makes bread rise.
The yeast cells in bread dough ferment sugars and produce gas (carbon dioxide). This makes the dough rise.
Yeast makes the bread rise.
Yeast respires, producing carbon dioxide that makes the bread rise
Baking yeast makes food rise and gives it a fluffy taste and feel to your food.

Yeast foams up when it feeds on sugar and produces carbon dioxide gas as a byproduct through fermentation. As the gas is trapped in the liquid, it creates bubbles and causes the mixture to foam. This process is essential in baking as the carbon dioxide helps dough rise.
it doesn't rise up because the yeast makes the bread expand.
