Enzymes are made up of

Options

A. edible proteins
B. proteins with specific structure
C. nitrogen containing carbohydrates
D. carbohydrates.

Answer

**Step-by-Step Solution:**

1. **Understanding Enzymes**: Enzymes are biological catalysts that speed up chemical reactions in living organisms. They are crucial for various biochemical processes.

2. **Composition of Enzymes**: Enzymes are primarily composed of proteins. Proteins are large, complex molecules made up of smaller units called amino acids.

3. **Amino Acids and Peptide Bonds**: Amino acids are linked together by peptide bonds to form polypeptides. The sequence and arrangement of these amino acids determine the structure and function of the enzyme.

4. **Structure of Proteins**: Proteins have different levels of structure:
- **Primary Structure**: The linear sequence of amino acids.
- **Secondary Structure**: The folding or coiling of the polypeptide chain into structures like alpha-helices and beta-sheets.
- **Tertiary Structure**: The three-dimensional shape formed by the entire polypeptide chain.
- **Quaternary Structure**: The arrangement of multiple polypeptide chains in a multi-subunit protein.

5. **Specificity of Enzymes**: Each enzyme has a specific structure that determines its function. This specificity is crucial for the enzyme's ability to catalyze particular reactions.

6. **Conclusion**: Therefore, enzymes are made up of proteins, which are themselves composed of amino acids linked by peptide bonds.

**Final Answer**: Enzymes are made up of proteins.
