Solution
Bacterial enzymes such as catalase and superoxide dismutase can protect bacteria from Phagocytic digestion.
Here's the step by step explanation:
-
Phagocytic digestion is a process where certain cells (phagocytes) engulf bacteria to destroy them.
-
The enzymes catalase and superoxide dismutase are produced by bacteria to neutralize harmful substances produced by phagocytes during this process.
-
Catalase breaks down hydrogen peroxide, a toxic byproduct of metabolism in aerobic organisms, into water and oxygen. This prevents damage to the bacterial cell.
-
Superoxide dismutase detoxifies superoxide, another harmful byproduct, by converting it into oxygen and hydrogen peroxide (which is then broken down by catalase).
-
Therefore, these enzymes protect bacteria from the destructive effects of substances produced during phagocytic digestion.
