Fill in the blanks with appropriate enzymes that are required for the following changes.

Options

A. Trypsinogen `overset(?)rarr` Trypsin
B. Caesin `overset(?)rarr` Paracasein+Whey proteins
C. RNA `overset(?)rarr` Ribonucleotides
D. Triglycerides `overset(?)rarr` Fatty acids +Glycerol

Answer

To fill in the blanks with the appropriate enzymes required for the specified changes, we can break down each transformation step by step:

1. **Trypsinogen to Trypsin**:
- **Enzyme**: Enterokinase
- **Explanation**: Trypsinogen is an inactive precursor (zymogen) produced by the pancreas. It is activated to trypsin by the enzyme enterokinase, which is secreted by the intestinal mucosa. Trypsin is a proteolytic enzyme that helps in the digestion of proteins.

2. **Casein to Paracasein**:
- **Enzyme**: Renin
- **Explanation**: Casein is a milk protein that is converted into paracasein by the enzyme renin (also known as rennet). This process is important in the coagulation of milk, which is essential for cheese production.

3. **RNA to Ribonucleotides**:
- **Enzyme**: Ribonuclease
- **Explanation**: Ribonuclease is the enzyme responsible for breaking down ribonucleic acid (RNA) into its constituent ribonucleotides. This is crucial for the recycling of nucleotides and the overall metabolism of nucleic acids.

4. **Triglycerides to Fatty Acids and Glycerol**:
- **Enzyme**: Lipase
- **Explanation**: Lipase is the enzyme that catalyzes the hydrolysis of triglycerides into glycerol and free fatty acids. This process is essential for the digestion and absorption of dietary fats.

### Summary of Answers:
- Trypsinogen → Trypsin: **Enterokinase**
- Casein → Paracasein: **Renin**
- RNA → Ribonucleotides: **Ribonuclease**
- Triglycerides → Fatty Acids + Glycerol: **Lipase**
