WebRibosomes may be attached to either the cytoplasmic side of the plasma membrane or the cytoplasmic side of the rough endoplasmic reticulum (Figure 2). ... Ribosomes receive their “orders” for protein synthesis from … WebThe Plasma Membrane. Like prokaryotes, eukaryotic cells have a plasma membrane ( Figure 3.8) made up of a phospholipid bilayer with embedded proteins that separates the internal contents of the cell from its surrounding environment. A phospholipid is a lipid molecule composed of two fatty acid chains, a glycerol backbone, and a phosphate group.
