(a) According to the De Broglie relation on wave-particle duality, the wavelength of electrons is a lot longer that the wavelength of photons. TRUE FALSE (b) In single-particle cryo-electron microscopy, samples are irradiated with an electron beam, and structural information is gained from the refraction of the incident electrons transmitted through a vitrified sample on a grid containing the biomolecule of interest. TRUE FALSE (c) Electrons used in single-particle cryo-electron microscopy have higher energy that the photons used in X-ray crystallography. Sample damage is therefore an important factor to consider in single- particle cryo-electron microscopy. TRUE TRUE FALSE (d) Cryo-EM instruments with a higher accelerating voltage supply electrons with a smaller linear momentum. FALSE (e) The resolving power of cryo-EM decreases as the accelerating Voltage increases.
