6.2: CATALASE - BIOLOGY LIBRETEXTS
ウェブ 2021年8月1日 If you have used hydrogen peroxide to clean a cut, you have seen catalase in action. When hydrogen peroxide comes in contact with the cut, it reacts with the catalase enzyme in the damaged cells to produce oxygen foam. When the catalase reaction is conducted in a test-tube, the oxygen gas bubbles.
