Understand the role of yeast in the production of beer
Beer-- composed largely ethanol, which is a kind of alcohol
Equation = Glucose --Yeast/Enzyme--> Ethanol + Carbon Dioxide
This reaction is in the form of anaerobic respiration which is carried out by yeast, which is a kind of microorganism able to supply the enzyme, to bring about this convert ion.
Ethanol is often flavored by the addition of plants such as hops.
Glucose comes from starch in a two step process:
1. Starch -----> Maltose
Enzyme: amylase
Source: Barley seeds, wheat seed, rice
Starch is broken down through amylase through the germination of the seed, which is the stage called malting.
2. Maltose -----> Glucose
Enzyme: Maltase
