Consider the given two statements:
Assertion (A): Fermentation is a type of anaerobic respiration where glucose is partially oxidized to produce energy.
Reason (R): Fermentation results in the production of ethanol or lactic acid without the use of oxygen.
  
1. Both (A) and (R) are True and (R) correctly explains (A).
2. Both (A) and (R) are True but (R) does not correctly explain (A).

Consider the given statements:

Statement I:  In alcohol fermentation in yeast, pyruvic acid decarboxylase and alcohol dehydrogenase convert pyruvic acid to carbon dioxide and ethanol.
