The process by which yeast produces the carbon dioxide responsible for bread rising is through cellular respiration.
The process by which yeast produces carbon dioxide responsible for bread rising is called cellular respiration. To understand this, let's break down the process:
1. Yeast is a microorganism that belongs to the fungi kingdom. It feeds on sugars, such as glucose, present in the dough when making bread.
2. During cellular respiration, yeast breaks down glucose molecules in the dough through a series of enzymatic reactions.
3. One of the byproducts of cellular respiration is the release of carbon dioxide (CO2) gas. This happens when yeast converts glucose into energy in the form of ATP (adenosine triphosphate).
4. The CO2 gas produced by yeast gets trapped within the dough, creating bubbles and causing the bread to rise.
In summary, yeast carries out cellular respiration to obtain energy from glucose, and carbon dioxide is released as a byproduct of this process, leading to bread rising.
