how does hydrogen peroxide kill bacteria
Answer ( 1 )
Hydrogen peroxide kills bacteria by breaking down their cell membranes and damaging their DNA. When hydrogen peroxide comes into contact with bacteria, it reacts with enzymes called catalases, which are present in most bacteria. This reaction produces oxygen and water, as well as free radicals such as hydroxyl radicals, which are highly reactive and can damage bacterial cell membranes and DNA. As a result, the bacteria are unable to survive and are effectively killed. This is why hydrogen peroxide is commonly used as an antiseptic to clean wounds and disinfect surfaces.
