Exnzyme concerned with the transfer of electrons is

Options

A. hydrolase
B. Dehydrogenase
C. Transaminease
D. Protease

Answer

To answer the question regarding which enzyme is concerned with the transfer of electrons, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for an enzyme that is specifically involved in the transfer of electrons. This indicates that we are looking for an enzyme that plays a role in redox (reduction-oxidation) reactions.

2. **Identifying Relevant Enzyme Class**: Enzymes that facilitate the transfer of electrons are classified under a specific category known as oxidoreductases. This class of enzymes is responsible for oxidation-reduction reactions, where electrons are transferred from one molecule to another.

3. **Focusing on Specific Enzymes**: Within the oxidoreductase class, there are various enzymes, one of which is dehydrogenase. Dehydrogenases are a subset of oxidoreductases that specifically catalyze the removal of hydrogen (which involves the transfer of electrons).

4. **Conclusion**: Based on the information gathered, the enzyme that is concerned with the transfer of electrons is **dehydrogenase**.

### Final Answer:
The enzyme concerned with the transfer of electrons is **dehydrogenase**.
