So the question given is basically from question of one to five and we need to write down the chemical reaction, the role of the yeast, we need to give five local sources and we need to enumerate the important use of the pharmaceutical and also the consumption of fruit wine and it's beneficial.
00:21
So first one, we have number one.
00:23
We should always remember that the alcohol production is done by fermentation.
00:28
Fermentation.
00:31
And fermentation is the chemical process of converting sugar present in fruits like grapes into alcohol.
00:38
So the chemical formula will be c6 h12 -06 yields to two most of c2h5 -oh plus two most of carbon dioxide.
00:50
Second, the yeast use in fermentation as a catalyst to catalyze a series of reaction to convert sugar into an alcohol.
01:00
And basically this is known as the alcoholic fermentation.
01:05
So alcoholic fermentation is only carried out in the absence of oxygen because in presence of oxygen, that would be aerobic condition.
01:16
The sugar is converted.
01:19
So basically the sugar will be converted into h2o and carbon dioxide.
01:27
Therefore, alcoholic fermentation is carried out under a blanket to exclude oxygen and hence maximize yield of alcohol.
01:36
Third, we have five local sources of starch...
