What phase 1 reaction is mainly performed by the cytochrome P450 enzymes also called mixed-function enzymes?

oxidation reactions are mainly performed by the cytochrome P-450 enzymes.

Explanation:

The main purpose of the phase 1 metabolism is to convert hydrophobic compounds into more reactive or polar groups so that they can be excreted out easily.Here,three reactions takes place:oxidation,reduction and hydrolysis.

Oxidation reaction is the most common reaction of phase 1 and it is typically carried out by cytochrome P-450 enzyme system.

Cytochrome P-450 are located in endoplasmic reticulum in liver tissues. They are member of a superfamily of monoxygenases that catalyze the oxidative metabolism of xenobiotics,the initial step in biotransformation and elimination of wide variety of drugs and other environmental pollutants.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
