Answer 2

Answer:

Correct option - (1) Heme protein, flavoprotein, phosphatidylcholine.

The 3 proteins involved in the multienzyme mixed-function oxidase system, located in the endoplasmic reticulum are heme protein, flavoprotein, and phosphatidylcholine.

Explanation:

For the oxidase system in the cells, there is a multi-enzyme complex made up of proteins.

• Heme protein contains a heme prosthetic group. It is composed of a ring-like organic compound named porphyrin to which iron atoms get attached. Heme helps in oxidizing the incoming substrates.
• Flavoproteins are the proteins that have the derivative of nucleic acid known as riboflavin. Flavoprotein functions as an electron carrier. It reduces cytochrome 450 to its ferrous form.
• A phosphatidylcholine is a group of phospholipids. They help in transferring electrons from NADPH to cytochrome 450.
