Which group contains biocatalysts

Options

A. Peptidase, amylase, rennin
B. Myosin, oxytocin, adrenalin
C. Rhodopsin, pepsin, steapsin
D. Glucose, amino acids, fatty acids

Explanation

To determine which group contains biocatalysts, we need to understand what biocatalysts are and identify examples of them.

### Step-by-Step Solution:

1. **Define Biocatalysts**:
- Biocatalysts are substances that accelerate chemical reactions in biological systems. The most common biocatalysts are enzymes.

2. **Identify Examples of Enzymes**:
- Enzymes are proteins that act as biocatalysts. Some examples include:
- **Peptidase**: An enzyme that breaks down peptides into amino acids.
- **Amylase**: An enzyme that breaks down starch into sugars.
- **Renin**: An enzyme involved in the digestion of milk proteins.

3. **Evaluate Other Options**:
- Look at other substances mentioned:
- **Glucose**: A simple sugar, not an enzyme.
- **Amino Acids**: The building blocks of proteins, not enzymes.
- **Fatty Acids**: Components of lipids, not enzymes.
- **Rhodopsin**: A pigment in the retina, not an enzyme.

4. **Select the Correct Group**:
- From the examples of enzymes listed, the group containing biocatalysts is:
- **Peptidase, Amylase, and Renin**.

5. **Conclusion**:
- Therefore, the correct answer to the question "Which group contains biocatalysts?" is the group that includes peptidase, amylase, and renin.

### Final Answer:
The group that contains biocatalysts is **Peptidase, Amylase, and Renin**.
