Which enzyme is required in final step of alcohol fermentation?

Expert Solution

Alcohol fermentation is also known as ethanol fermentation
Sugar molecules like sucrose, glucose, and fructose is getting converted into ethanol and carbon dioxide and producing energy for the cellular metabolism.
The diagram showing alcohol fermentation is attached below, there are 3 steps in it
Step A: This step is called glycolysis since the glucose molecule is cleaved into two pyruvate molecules.An oxidation reaction is occurring and glucose is converted to pyruvate
Step B: Decarboxylation(removal of CO₂)of pyruvate to form acetaldehyde by the enzyme pyruvate decarboxylase
Step C: Reduction of acetaldehyde to form ethanol.This step is the last step and is catalyzed by the enzyme Alcohol dehydrogenase. So the enzyme required for the final step of alcohol fermentation is Alcohol dehydrogenase.
The abbreviations of NADH, ATP, and ADP are Nicotinamide adenine dinucleotide, Adenosine triphosphate and adenosine diphosphate respectively.
NADH is a coenzyme which is essential for the activity of the enzymes.
ATP and ADP are energy storage molecules which on interconversion releases lot of energy which is used for the biological processes.
During fermentation, the energy is stored in the ATP molecule and is cleaved to release energy whenever the body is doing some work.

The human pathway for metabolizing alcohol starts with the enzyme alcohol dehydrogenase, which catalyzes the conversion of ethanol (C2H5OH) to acetaldehyde (CH3CHO). This is followed by the aldehyde dehydrogenase 2 (ALDH2, the enzyme of interest in this problem), which catalyzes the conversion of acetaldehyde and HS-CoA to acetyl-CoA (CH3CO–S–CoA). The TCA cycle starts and oxidizes the acetyl-CoA to CO2. Draw two diagrams of this pathway—one for an individual without AFS and another for an individual with AFS. How ALDH2 deficiency...

An enzyme acts as a catalyst in the fermentation of A to form product R. An aqueous feed stream containing the enzyme and compound A flows into a CSTR at 25 L/min, and the initial concentration of A is 2 mol*L-1 . Determine the volume of the CSTR (in Liters, expressed to the nearest integer ) needed to achieve 98% conversion of reactant A. You may assume that the enzyme concentration and volumetric flowrates are constant. The maximum rate of...

The formation of ethyl alcohol (C2H5OH MM = 46.08 g/mol) by the fermentation of glucose (C6H12O6 MM = 180.18 g/mol) may be represented by: C6H12O6 → 2C2H5OH + 2CO2 If a particular glucose fermentation process is 87.0% efficient, how many grams of glucose would be required for the production of 56.0 g of ethyl alcohol (C2H5OH)?

Yeast make alcohol in the absence of oxygen by a process called fermentation (i.e., anaerobic respiration). Complete fermentation of one of the sugar glucose (C6 H12 O6) will generate two moles of ethanol (C2 H6 O), two moles of carbon dioxide (CO2) gas, and tow moles of the important molecule ATP (C10 H16 N5 O13 P3), using in cellular transfers. You perform an experiment to make alcohol, so you set up an anaerobic fermentation system using yeast. You add 135...
