Solution

Bacterial enzymes such as catalase and superoxide dismutase can protect bacteria from Phagocytic digestion.

Here's the step by step explanation:

  1. Phagocytic digestion is a process where certain cells (phagocytes) engulf bacteria to destroy them.

  2. The enzymes catalase and superoxide dismutase are produced by bacteria to neutralize harmful substances produced by phagocytes during this process.

  3. Catalase breaks down hydrogen peroxide, a toxic byproduct of metabolism in aerobic organisms, into water and oxygen. This prevents damage to the bacterial cell.

  4. Superoxide dismutase detoxifies superoxide, another harmful byproduct, by converting it into oxygen and hydrogen peroxide (which is then broken down by catalase).

  5. Therefore, these enzymes protect bacteria from the destructive effects of substances produced during phagocytic digestion.
