Expert Solution
Step 1
a) Reaction a is catalysed by Isomerase.
Reason: In the reaction shown in (a) is L- alanine getting converted into D-alanine .The reactions involving this sort of structural rearrangement are catalysed by isomerase.
b) The reaction is catalysed by the enzyme Pyruvate decarboxylase.
Reason: In the given reaction, pyruvate is getting converted to ethanol and CO2.As the CO2 molecule is being removed from pyruvate the enzyme pyruvate decarboxylase is used.
