Proteins are actually vital components of the plasma membrane that are involved in various functions such as transport, cell recognition, and cell signaling. They are not considered part of the nonactive matrix of the plasma membrane. Lipids make up the majority of the membrane structure, determining its fluidity and stability.
No, the plasma membrane does not produce proteins. Proteins are synthesized by ribosomes in the cytoplasm and then transported to the plasma membrane to carry out various functions such as transport, signaling, and cell adhesion.
No, peripheral steroids are not part of the plasma membrane. Peripheral steroids are molecules found in the cytoplasm and do not directly interact with the plasma membrane. The plasma membrane is primarily composed of phospholipids, proteins, and cholesterol.
Proteins embedded in the plasma membrane are called integral membrane proteins. These proteins are permanently attached to the lipid bilayer and play important roles in various cellular functions such as cell signaling, transport, and cell recognition.
The cell membrane contains the membrane proteins that enable a hormone to selectively bind to its plasma membrane. These proteins, such as receptor proteins, are responsible for recognizing and binding to specific hormones, allowing the hormone to exert its effects on the cell.

The cells are often bound to the extracellular matrix by proteins in the plasma membrane. The extracellular matrix is the structural support of tissue.

DNA, proteins, plasma membrane
Proteins attached to only one side of the plasma membrane are known as monotopic proteins. These proteins are anchored to the membrane through a single hydrophobic region, rather than spanning the entire membrane like transmembrane proteins. Monotopic proteins play a variety of roles in cell signaling, transport, and structural support.
They are called integral proteins
The proteins of the plasma serve the function of acting as porins. Porins are channels control the transport of substances in and out of the cell, imparting the membrane its property of semipermeabililty. Also, proteins make up 60-70% of the plasma membrane and thus form the bulk of it. Besides, the proteins are also involved in some important cellular reations.
Both the inner and outer leaflets of the plasma membrane in a cell have intrinsic and extrinsic protein molecules embedded within the phospholipid bilayer. Intrinsic proteins are integral membrane proteins that span the membrane, while extrinsic proteins are peripheral membrane proteins that are attached to the surface of the membrane.
Like all other cellular membranes, the plasma membrane consists of both lipids and proteins
