Many proteins are secreted in their inactive form . This is also true to may toxic proteins produced by microorganisms. Explain how the mechanism is useful for the organism producing the toxin ?

Explanation

**Step-by-Step Solution:**

1. **Introduction to Inactive Proteins**: Many organisms, including microorganisms, secrete proteins in an inactive form. This is particularly true for toxic proteins that can harm other organisms.

2. **Example of Bacillus thuringiensis**: A classic example is the bacterium Bacillus thuringiensis, which produces an insecticidal protein. This protein is secreted in an inactive form as an endotoxin.

3. **Function of the Inactive Form**: The inactive form of the protein ensures that it does not harm the organism itself (Bacillus thuringiensis). This is crucial for the survival of the producing organism, as it prevents self-damage.
