What level of structural organization do voltage-gated sodium channels in muscle sarcolemma represent? what level of structural organization do voltage-gated sodium channels in muscle sarcolemma represent? cellular organ molecule tissue?

The correct answer is a molecule.  

It is relevant to consider the compositions of the body in terms of basic levels of the organization, which enhance in complexity: subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms, and biosphere.  

The voltage-gated sodium channels come under the molecule level of structural organization. It plays an essential role in action potentials.  

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.
