Write an experiment to observe the production of alcohol in the lab.
Answers
Answer:
Fermentation is the chemical breakdown of a substance by bacteria, yeast or other microorganisms.
Maida is used in making bread and other bakery products.
The main ingredient used in making bread is Baker's yeast.
Yeast is added for preparing the dough.
Yeast gets activated in the presence of sugar and thus helps in fermentation.
It contains the following enzymes:-
1) Amylase - changes a small amount of starch into maltose.
2) Maltase - changes maltose to glucose.
3) Zymase - Zymase complex acts on glucose to form ethyl alcohol and carbon dioxide.
Production of carbon dioxide causes the dough to rise, this is called leavening or rising.
The left dough is baked.
The bread obtained is soft and fluffy.
The sponginess is due to expulsion of carbon dioxide and alcohol.
Answer:
Biorenewables Education Laboratory ... This experiment will track three parameters throughout the fermentation: glucose ... production of ethanol, which is eventually toxic to the yeast.
