Which of the following terms are correct about enzyme?

Options

A. Proteins
B. Dinucleotides
C. Nucleic acids
D. Biocatalysts

Explanation

To determine which terms are correct about enzymes, let's analyze each option provided in the question:

1. **Protein**: Enzymes are primarily composed of proteins. They are biological catalysts that speed up chemical reactions in the body without being consumed in the process. Therefore, this term is correct.

2. **Dinucleotides**: Dinucleotides are molecules made up of two nucleotides and are not related to enzymes. They are involved in cellular energy transfer and signaling, but they do not describe enzymes. Thus, this term is incorrect.

3. **Nucleic Acid**: Nucleic acids, such as DNA and RNA, are polymers made up of nucleotide monomers. They are not enzymes; rather, they serve as genetic material and are involved in protein synthesis. Hence, this term is also incorrect.

4. **Biocatalyst**: Enzymes are indeed biocatalysts, meaning they facilitate biochemical reactions without being altered in the process. This term is correct.

In conclusion, the correct terms about enzymes from the options given are:
- Protein
- Biocatalyst

**Final Answer**: The correct terms about enzymes are:
- Protein
- Biocatalyst
