Which of the following statements is incorrect?

Options

A. Enzymes exist in colloidal state
B. Enzymes are catalysts
C. Enzymes can catalyse any reaction
D. Urease in an enzyme

Answer

To determine which statement about enzymes is incorrect, we will analyze each of the four statements provided:

1. **Enzymes exist in the colloidal state.**
- Enzymes are large macromolecules, typically proteins, and they are indeed insoluble in water, which allows them to exist in a colloidal state. This statement is **true**.

2. **Enzymes are catalysts.**
- Enzymes function as biological catalysts that speed up chemical reactions in living organisms. This statement is also **true**.

3. **Enzymes can catalyze any reaction.**
- This statement is incorrect. Enzymes are highly specific and can only catalyze particular reactions based on their structure and the specific substrates they bind to. This statement is **false**.

4. **Urease is an enzyme.**
- Urease is indeed an enzyme that catalyzes the hydrolysis of urea into ammonia and carbon dioxide. This statement is **true**.

Based on the analysis, the incorrect statement is:

**Enzymes can catalyze any reaction.**
