Verified step by step guidance

Understand the concept of cell communication: Cells communicate with each other through signaling molecules, which are often proteins or other types of molecules that can bind to receptors on the cell surface.

Identify the role of cell surface receptors: Cell surface receptors are specialized proteins located on the cell membrane that bind to signaling molecules. This binding is crucial for initiating a cellular response.

Differentiate between the options: Analyze each statement to determine which accurately describes the function of cell surface receptors. Consider how receptors interact with signaling molecules and what happens after binding.

Focus on the correct function: Cell surface receptors do not transport ions for energy generation, degrade signaling molecules, or directly synthesize proteins. Their primary role is to bind signaling molecules and initiate a cellular response.

Conclude with the correct description: The statement 'They bind to signaling molecules and initiate a cellular response' best describes the role of cell surface receptors in cell communication.
