For the enzymatically catalyzed reactions shown below, classify the enzymes as oxidoreductases, transferases, hydrolases, lyases, isomerases, or ligases. answer parts (a), (b), and (c). g

I found the full exercise on the internet. Attached are the images of enzymatically catalyzed reactions.

Reaction a) - acyl phosphate to carboxylate and phosphate.
The enzyme that catalyses this reaction is the acylphosphatase, which is a hydrolase, because it uses molecules of water in the reaction.

Reaction b) - ATP + an L-amino acid + an L-amino acid to ADP + phosphate + L-aminoacyl-L-amino acid.
The enzyme that catalyses this reaction is the L-amino-acid alpha-ligase, which is a ligase because it preforms the bonding of two large molecules.

Reaction a) - glucose-1-phosphate to glucose-1,6-bisphosphate to glucose-6-phosphate
The enzyme that catalyses this reaction is the Glucose-1,6-bisphosphate synthase, which is a transferase because it transfers a phosphate group from a donating to an accepting molecule.

Reaction b) - + to NADH+
The enzyme that catalyses this reaction is a oxidoreductase because it helps oxidising and reducing molecules.

Reaction c) - α-keto acid + Glutamate to Aminoacid + α-ketoglutarate
The enzyme that catalyses this reaction is an aminotransferase, which is a transferase because it transfers an amino group from a donating to an accepting molecule.

Reaction c) - produces a molecule of 
The enzyme that catalyses this reaction is a Carboxy-lyase, which is a lyase because it adds or removes carboxyl groups from organic molecules.
