### Enzyme Naming Questions

#### Question a:
**What would be the appropriate name for an enzyme that catalyzes each of the following reactions:**

A reaction is displayed in which the chemical compound changes from:
- **Reactant:** Alanine (with the chemical formula \( \text{H}_3\text{C}-\text{C}(=O)-\text{OH} \quad \text{NH}_2 \)) 
- **Product:** An alanine derivative (with the chemical formula \( \text{H}_3\text{C}-\text{C}(=O)-\text{OH} \quad \text{NO}_2 \))

**Options:**
- o Alanine ligase
- o Alanine oxidoreductase
- o Alanine isomerase
- o Alanine transferase

#### Question b:
**What would be the appropriate name for an enzyme that catalyzes each of the following reactions:**

A reaction is displayed in which the chemical compound changes from:
- **Reactant:** Propan-2-ol (with the chemical formula \( \text{HO}-\text{CH}_2(\text{CH}_3) \))
- **Product:** Propanone (with the chemical formula \( \text{O}=\text{CH}_2(\text{CH}_3) \))

**Options:**
- o Propanone transferase
- o Propan-2-ol hydrolase
- o Propan-2-ol oxidoreductase
- o Propan-2-ol isomerase

### Explanation of Diagrams
- **Diagram for Reaction (a):** This diagram shows a chemical reaction where an amino group (\( -\text{NH}_2 \)) in the reactant alanine is replaced with a nitro group (\( -\text{NO}_2 \)) in the product.
- **Diagram for Reaction (b):** This diagram shows a chemical reaction where a hydroxyl group (\( -\text{OH} \)) in propan-2-ol is converted to a carbonyl group (\( =\text{O} \)) forming propanone.
