Question

What electron microscope technique is well suited for capturing subunit structures of high-molecular weight aggregates like viruses, ribosomes, multisubunit enzymes, and protein complexes? The specimen in the resulting micrograph stands out because they are brighter than the viewing screen

Answer 1

Transmission Electron Microscopy (TEM) is the electron microscope technique that is well suited for capturing subunit structures of high-molecular weight aggregates like viruses, ribosomes, multisubunit enzymes, and protein complexes.

Step-by-step explanation:

The electron microscope technique that is well suited for capturing subunit structures of high-molecular weight aggregates like viruses, ribosomes, multisubunit enzymes, and protein complexes is Transmission Electron Microscopy (TEM).

TEM accelerates electrons that are emitted from a hot filament, and the beam passes through the sample. A magnetic lens focuses the beam image onto a fluorescent screen, a photographic plate, or a light sensitive camera. The resulting micrograph in TEM stands out because the specimens are brighter than the viewing screen.
