An example of a biocatalyst is

Options

A. Amino acid
B. Enzyme
C. Carbohydrate
D. DNA

Answer

**Step-by-Step Text Solution:**

1. **Understanding Biocatalysts:**
- A biocatalyst is a substance that accelerates a chemical reaction in biological processes. The term "bio" refers to life or living organisms, while "catalyst" refers to a substance that increases the rate of a reaction without being consumed in the process.

2. **Identifying the Options:**
- The question provides several options, and we need to determine which one qualifies as a biocatalyst. The options include:
- A) Amino Acids
- B) Enzymes
- C) Carbohydrates
- D) DNA

3. **Analyzing Each Option:**
- **Amino Acids:**
- These are organic compounds that serve as the building blocks of proteins. While they are essential for various biological functions, they do not act as catalysts themselves.
- **Enzymes:**
- Enzymes are proteins that function as biocatalysts. They speed up reactions by lowering the activation energy required for the reaction to occur. Therefore, they are indeed biocatalysts.
- **Carbohydrates:**
- These are biomolecules made up of carbon, hydrogen, and oxygen. They serve as energy sources and structural components but do not act as catalysts.
- **DNA:**
- DNA (deoxyribonucleic acid) contains the genetic information of organisms. It does not catalyze reactions but rather serves as a blueprint for protein synthesis.

4. **Conclusion:**
- Based on the analysis, the only option that qualifies as a biocatalyst is **B) Enzymes**.

**Final Answer:** Enzymes are an example of a biocatalyst.
