Verified step by step guidance

Understand the role of proteins in the plasma membrane. Proteins in the plasma membrane have various functions, including acting as receptors, channels, and facilitators of cell communication.

Identify the function of proteins as receptors for signal transduction. Proteins can bind to signaling molecules, initiating a cellular response.

Recognize the function of proteins as channels for ions and molecules. These proteins form pathways that allow specific substances to pass through the membrane.

Consider the role of proteins in cell-cell recognition and communication. Proteins on the cell surface can interact with proteins on other cells, facilitating communication and recognition.

Evaluate the statement about structural support. Proteins in the plasma membrane do not form the cytoskeleton; the cytoskeleton is composed of different types of proteins within the cell, not the membrane itself.
