Textbook Question

Answer questions (a)–(e) concerning the following reaction:

a. The enzyme involved in this reaction belongs to what class of enzymes?

Verified step by step guidance

Identify the type of reaction occurring in the given chemical equation. Enzyme classes are categorized based on the type of reaction they catalyze, such as oxidation-reduction, hydrolysis, or isomerization.

Review the six main classes of enzymes: oxidoreductases, transferases, hydrolases, lyases, isomerases, and ligases. Each class corresponds to a specific type of reaction.

Analyze the reaction provided in the problem (e.g., does it involve the transfer of electrons, breaking of bonds with water, or rearrangement of atoms within a molecule?).

Match the observed reaction type to the appropriate enzyme class. For example, if the reaction involves the addition or removal of water, the enzyme is likely a hydrolase.

Conclude the enzyme class based on the reaction's characteristics and provide reasoning for the classification.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Enzyme Classification

Enzymes are classified into six main categories based on the type of reaction they catalyze: oxidoreductases, transferases, hydrolases, lyases, isomerases, and ligases. Understanding the specific class of an enzyme helps in identifying its function and the biochemical processes it facilitates.

Enzyme Function

Enzymes are biological catalysts that speed up chemical reactions in living organisms by lowering the activation energy required. Each enzyme has a specific substrate it acts upon, and its activity can be influenced by factors such as temperature, pH, and the presence of inhibitors or activators.

Reaction Mechanism

The reaction mechanism describes the step-by-step process by which an enzyme converts substrates into products. This includes the formation of enzyme-substrate complexes and the transition states, which are crucial for understanding how enzymes achieve their catalytic effects and the overall kinetics of the reaction.
