Roles of Proteins and Glycoproteins in Cell Membranes Steps:

• Identify key functions: proteins act as channels, receptors, and enzymes; glycoproteins aid in cell recognition and adhesion.
• Evaluate statement 1: proteins provide structural support and transport—correct per fluid mosaic model.
• Evaluate statement 2: glycoproteins enable immune response and signaling—correct as they form the glycocalyx.
• Evaluate statement 3: both are embedded or peripheral in the phospholipid bilayer—correct based on membrane composition.

Not enough information: Statements 1, 2, and 3 are not provided, preventing full verification.

Final answer: Not enough information.
