Yes it is !
Integral proteins are membrane proteins that are permanently attached to the membrane phospho lipid bilayer.ATPase enzyme is an example for the integral proteins which make ATP. Peripheral proteins in contrast present on the surface of the membrane.
No, they are not. Phospholipids, intergral proteins and glycolipids are however.
Proteins are not primary components of cell membrane. The proteins on the cell membrane have special functions, like receptors and transporters.
They help control what enters and leaves the cells.

Membrane proteins have a variety of functions. They relay signals between the cell's inside and outside environments. Transport proteins move the molecules across the membrane.

No, the site of protein synthesis is the ribosomes, free and bound. The ribosome is the " workbench " on which proteins are made. Proteins can be imbedded in the membrane and can span the membrane.
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.
Globular proteins act as enzymes and catalyze organic reactions. They also transmit messages to regulate biological processes. Globular Proteins transport molecules through the membrane, and act as regulators within the membrane.
The membrane of the RER contains ribosomes. This is what makes the membrane "rough". The function of the ribosomes is to produce proteins.
