Answer:
Some proteins within a cell can be viewed with the "Electron microscope".
Explanation:
An electron microscope is a laboratory microscope with a singular beam that uses electrons to refract the surface of objects and picture an image. They can improve the reach of light photons. So, they mean a really big improvement. They are used to study molecules, microorganisms, crystals and more tiny objects. Thus, that is why electron microscopes can reach proteins inside the cells.
