ethanol can be obtained by fermentation of​

Answer 1

Answer:

$\underline{\huge{Answer:-}}$

Aqueous solutions of ethanol can be produced when sugar solutions are fermented using yeast. When yeast is added it feeds on the sugar in the absence of oxygen to form wine (a solution of ethanol) and carbon dioxide. ...

Answer 2

Ethanol can be obtained by fermentation of yeast.

• In organisms like yeast, pyruvic acid is formed by partial oxidation of glucose and it is then converted to ethanol and CO2 (carbon dioxide). This process is called alcoholic or ethanol fermentation.
• Here a chemical reaction takes place which is called fermentation.
• In the fermentation, ethanol is formed after glucose is broken down by the action of enzymes in the yeast.
• This chemical reaction is catalysed by the enzymes, pyruvic acid decarboxylase and alcohol dehydrogenase.
• Fermentation is actually an anaerobic pathway which is a common pathway in the majority of prokaryotes and unicellular eukaryotes. In the fermentation process, glucose is partially oxidised to form alcohol and acids.
