When an apple is injured (or cut into pieces), the plant tissue is exposed to oxygen. This triggers an enzyme known as polyphenol oxidase (PPO) to—wait for it—oxidize polyphenols in the apple's flesh. This results in new chemicals (o-quinones), which then react with amino acids to produce brown-colored melanins.
3.Each metal catalyst must be prepared in a special way: nickel is usually used in a finely divided form called “Raney nickel.” It is prepared by reacting a Ni-Al alloy with NaOH. palladium is obtained commercially “supported” on an inert substance, such as charcoal,
