Fermentation of Glucose to alcohol undergoes in presence of :a)ZnOb)Cr2O3c)Invertased)ZymaseCorrect answer is option 'D'. Can you explain this answer?

Question

Accepted Answer

The correct answer is option D
Zymase is an enzyme complex that catalyzes the fermentation of sugar into ethanol and carbon dioxide. It occurs naturally in yeasts. Zymase activity varies among yeast strains. Zymase is also the brand name of the drug pancrelipase.

Cell-free fermentation experiment

[

edit

]

Zymase was first isolated from the yeast cell in 1897 by a German chemist named

Eduard Buchner

who fermented sugar in the laboratory without living cells, leading to 1907 Nobel Prize in Chemistry.

The experiment for which Buchner won the Nobel Prize consisted of producing a cell-free extract of

yeast

cells and showing that this 'press juice' could ferment sugar. This dealt yet another blow to

vitalism

by showing that the presence of living yeast cells was not needed for fermentation. The cell-free extract was produced by combining dry yeast cells,

quartz

and

kieselguhr

and then pulverizing the yeast cells with a mortar and pestle. This mixture would then become moist as the yeast cells' contents would come out of the cells. Once this step was done, the moist mixture would be put through a press and when this resulting 'press juice' had

glucose

,

fructose

, or

maltose

added,

carbon dioxide

was seen to evolve, sometimes for days. Microscopic investigation revealed no living yeast cells in the extract.

Buchner hypothesized that yeast cells secrete proteins into their environment in order to ferment sugars. It was later shown that fermentation occurs inside the yeast cells.

British chemist Sir

Arthur Harden

divided zymase into two varieties (dialyzable and nondialyzable) in 1905.

Some science historians^[3] suggest that

Eduard Buchner

, in his 1897 work, merely repeated experiments already made by

Antoine B�champ

in 1857. This is not the case : what Buchner obtained with yeast zymase, and without yeast cells, was alcoholic fermentation, while B�champ had explicitly stated that, in absence of yeast cells, and by use of what he, also, called 'zymase', he obtained only sugar inversion and no alcoholic fermentation.^[4] According to K.L. Manchester,^[5] what B�champ called 'zymase' was

invertase

.

Answer

Glucose undergo fermentation in presence of Zymase enzyme ( obtained from yeast ) to give ethanol and CO2

Answer

Zymase helps in converting glucose to alcohol

Answer

Option d is correct answer bcoz it act as enzyme in this reaction

Answer

Explanation:

Fermentation of Glucose to Alcohol:

- Fermentation of glucose to alcohol is a biochemical process that occurs in the presence of enzymes.
- The key enzyme involved in this process is Zymase.

Zymase:

- Zymase is a complex of enzymes that catalyzes the fermentation of glucose to alcohol.
- It is derived from yeast and other microorganisms.
- Zymase consists of a group of enzymes that work together to break down glucose into alcohol and carbon dioxide.

Role of Zymase in Fermentation:

- Zymase plays a crucial role in the fermentation process by catalyzing the conversion of glucose into ethanol and carbon dioxide.
- The enzyme breaks down glucose molecules into smaller components that eventually form alcohol.

Importance of Zymase in Fermentation:

- Zymase is essential for the fermentation process to occur efficiently and produce alcohol.
- Without the presence of Zymase, the conversion of glucose to alcohol would not take place.

Therefore, the correct answer to the question is option 'D' Zymase, as it is the enzyme responsible for the fermentation of glucose to alcohol.
