The protein is anchored into the membrane by its nonpolar region, but the protein remains moblie. To explain it more, the middle section of the protein is made of many nonpolar amino acids. This nonpolar coil fits into the nonpolar interior of the lipid bilayer allowing the protein to float in the membrane.
Only special types of proteins can "sit" in the cell membrane. The inside of the cell membrane is highly hydrophobic, so a protein when folded with several neutral amino acids on the outside would be energetically favorable to be in the membrane. The outside edges of the membrane is hydrophillic, so a protein would want to have its charged amino acids on its ends so that they do not get stuck in the hydrophobic region of the membrane. If you look from the side, the hydrophillic charged amino acids of the protein should stick out of the membrane, and the hydrophobic neutral amino acids of the protein would be in between the bilayer.
They can go through the membrane (transmembrane) or stick out on one side of the membrane.
Membranes bound within the cell membrane. Integral proteins extend from one side of the membrane to the other.
Carrier proteins are proteins involved in the movement of ions, small molecules, or macromolecules, such as another protein, across a biological membrane. Carrier proteins are integral membrane proteins; that is, they exist within and span the membrane across which theytransportsubstances.
The two main proteins found in the cell membrane are integral proteins and peripheral proteins. Integral proteins are embedded within the membrane and can span across it, while peripheral proteins are located on the surface of the membrane and are not embedded within it. Both types of proteins play important roles in various cellular functions including transport, communication, and cell signaling.
no, lipid-anchor membrane protein are found within the lipid-bilyer and are covalently bonded, but paripheral membrane proteins and found on the out side of the membrane , either on the extracellular or the cytoplasm side ,and they bonded my hydrogen bond.

There are four functions of proteins within the cell membrane. The four functions of proteins are active transport, cell recognition, cell communications, and are used as enzymes in the cell membrane.

Ribosomes within the cytosol (if they are free) or within the endoplasmic reticulum (if they are membrane bound) are responsible for making proteins.

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.

Membrane proteins and all other proteins are produced in cytoplasm. The proteins targeted to membranes by specific signals. Golgi vesicles transport the proteins to membrane. Not all proteins are membrane proteins
