Identify the kind of chemical catalysis and then identify which of the following amino acids can act as a catalyst for each reaction. Answer parts a), b), and c). This is an example of Which amino acid would catalyze this reaction? This is an example of Which amino acid would catalyze this reaction? This is an example of Which amino acid would catalyze this reaction?

Answer 1

Concept and Reason

The concept used here is an enzyme catalysis. The enzyme enhances rate of reaction in different mechanisms that is by using metal ion catalysis, covalent catalysis, acid/base catalysis etc.

Fundamentals

Generally, an enzyme decreases the activation energy of the substrate in biochemical reactions by forming enzyme-substrate complex. The reduction of activation energy enhances the product formation at normal temperature and pressure.

(a)

The reaction is shown given below:

(b)

The reaction is shown given below:

(c)

The reaction is shown given below:

Ans: Part a

The reaction is an example of covalent catalysis reaction and lysine will catalyze it.

Part b

The reaction is an example of acid-base catalysis reaction and histidine will catalyze it.

Part c

The reaction is an example of acid-base catalysis reaction and glutamic acid will catalyze it.
