Answer
a). The first reaction catalysed by enzyme isomerase. Because, in the given compound L -alanine is convert into D-alanine (second position of the methyl group is rearranged from left to right). Hence, the final answer is isomerase is an enzyme that catalyses in the given reaction.
b). In the second reaction, the given compound is pyruvate and the products are ethanol and carbon dioxide. This reaction is catalysed by the enzyme pyruvate decarboxylase.( reaction type is decarboxylation. ) Hence, the final answer is pyruvate decarboxylase.
