on the go

i have been studying biology nonstop.

i love it but i hate it. 

shown above:

i instagramed this artsy fartsy three dimensional structure of photosystems II as determined by x-ray crystallography. psII is a big fat deal in photosynthesis because it can oxidize water (which includes oxidizing oxygen which isn’t something that can just happen) in the manganese cluster, which ultimately leads to the byproduct of oxygen from plants so all you bitches can breathe and not die.

i pray to god i do well on this exam. i never know how i'm going to do.
