Which of the following statements about alcoholic fermentation are correct?
I. It occurs in some yeasts and hepatocytes.
II. It’s a mechanism to reduce NAD+.
III. Acetaldehyde is an intermediate product.
IV. A decarboxylase plays a role in the process.
A. III and IV
B. I and II
C. II and III
D. I, II and III
E. II, III and IV
@ChuHtet would you mind sharing the answer as i have got one but ain’t sure whether it’s correct or not.
The answer says 3 and 4 only.
we can eliminate options to check which ones are correct:
- Alcoholic fermentation do occurs in Yeasts but hepatocytes don’t make sense as Humans cannot ferment alcohol in their own bodies.
- It’s mechanism for the generation of NAD+ from NADH so that it can be used in glycolysis for ATP generation.
- Acetaldehyde is formed as a intermediate: 2 pyruvate---->acetaldehyde------>2ethyl alcohol.
- Decarboxylase do plays a role it releases 2 CO2 to form acetaldehyde from 2 pyruvate.
Hope it makes sense:)
Thank you very much. This explains well.
