Detailed explanation-1: -Due to this integral membrane proteins are found within the structure of the cell membrane, while peripheral membrane proteins are found attached to the surface of the cell membrane.

Detailed explanation-2: -Peripheral membrane proteins are found on the outside and inside surfaces of membranes, attached either to integral proteins or to phospholipids. Unlike integral membrane proteins, peripheral membrane proteins do not stick into the hydrophobic core of the membrane, and they tend to be more loosely attached.

Detailed explanation-3: -Many peripheral proteins are also a part of many complex biochemical pathways. They can be involved in moving substances within or outside of a cell, activate other proteins and enzymes, or be involved in cell to cell interactions.

Detailed explanation-4: -Peripheral proteins are found just on the membrane’s surface and often engage in cellular response pathways or serve as receptors, enzymes, and cytoskeletal proteins. For example-cytochrome C and flavoproteins.
