A mole of light is called an Einstein, right? That is a mole of photons. And the characteristic absorbance in the 400 nanometer range displayed by molecules like cytochromes and photopigments is called the Soret band. The absorbance spectrum is the spectrum of light that a molecule, or rather could be a whole organism, will absorb. The action spectrum is the photosynthetic activity plotted over wavelength. And blue light is a type of light; it's not an absorbance. However, it is in this range, kind of a tricky answer choice there. And the alpha band, that is similar to the band, right? It was talked about at the same time, but the alpha band is a separate thing from the Soret band. The alpha band is the sort of characteristic absorbance. So the Soret band is shared by many molecules, but the alpha band is sort of what is the, like fingerprint for certain molecules if you will. It's unique to them. All right. That's all I have for this exam review. Good luck studying for your 6th exam and good luck studying for your final. I hope you guys do really well.
