Answer:
Yeast is a basic ingredient which causes the bread to rise.
Answer: 1. Flour is the third ingredient.
2. Carbon dioxide and Ethanol
are by-products that also
cause rising.
Explanation:
Bread rises in a process known as Fermentation. Fermentation is the process in which microorganisms such as yeast help to break down molecules like sugar in an anaerobic process, eventually giving off a gas and alcohol.
Ingredients required include; yeast, water, and flour. The mixture of yeast and water react with the sugar present in the flour to cause rising. Carbon dioxide and ethanol are then produced.
The gluten (which Is produced when flour proteins mix with water) in the dough mixture reacts with the carbon dioxide gas, making it hard for the gas to be emitted. This process causes rising.
As ethanol is given off and evaporating from the mixture, rising also occurs.
