Many proteins are secreted in their inactive form. This is also true of many 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 proteins, including toxic proteins produced by microorganisms, are secreted in an inactive form. This means that they are synthesized as precursors that require activation to become functional.

**Hint**: Consider why proteins might need to be inactive initially.

2. **Activation Conditions**: These inactive proteins often require specific environmental conditions, such as changes in pH or temperature, to become activated. This activation is crucial for their function.
