the answer is A. I took the test and got it right. The question is specifically asking about the THIN filaments, making it actin- and only actin.
Explanation:
-the specific binding of a region of the protein to solutes or a substrate
Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers or function as receptors.
These include receptor proteins that bind specifically to molecules called lingands; some also use channels which respond to chemical signals by modifying solute-specific regions that aid in regulating ion exchange, through the hydrophobic layer of the plasma membrane.
