(c)

Answer to Problem 15.33EP
No, glutarate and glutamate cannot function as the reactants in a transamination reaction.
Explanation of Solution
Glutarate is a diacid and its structure is:
Glutamate is an amino acid and its structure is:
The two reactants in transamination reaction are a keto acid and an amino acid. Glutamate is an amino acid but glutarate is not a keto acid. For a transamination reaction to take place there must be one keto acid present along with an amino acid. Thus, glutarate and glutamate cannot function as the reactants in a transamination reaction.

(d)

Answer to Problem 15.33EP
No, oxaloacetate and succinate cannot function as the reactants in a transamination reaction.
Explanation of Solution
Oxaloacetate is a keto acid and its structure is:
Succinate is a diacid acid and its structure is:
The two reactants in transamination reaction are a keto acid and an amino acid. Oxaloacetate is keto acid but succinate is not an amino acid. For a transamination reaction to take place there must be one amino acid present along with a keto acid. Thus, oxaloacetate and succinate cannot function as the reactants in a transamination reaction.
