To find out what factors affect how quickly bread dough rises.
There are a number of factors that affect how quickly bread dough rises. These are:
• Amount of sugar-if the amount of sugar is increased, the rate of reaction will increase. Adding a higher concentration of sugar will increase the sugar particles in a given space. As the mixture is heated, the sugar particles will begin to move. Due to a lack of space, this would result in collisions. Thus the rate of reaction would increase, resulting in the bread dough rising quickly.
• Concentration of yeast- if more yeast is added; the quicker the bread dough rises. Yeast contains an enzyme known as zymase. As the quantity of the yeast is increased, the enzyme would increase. As more zymase' are present, would result in more enzymes available for reaction. After these active sites are filled, only then would a reaction would take place. If less yeast is added bread dough would not rise- unleavened brea...
