Question
Members of this class of proteins are involved in the light-dependent sensing of magnetic fields in some animals. For 10 points each:
[10h] Name this class of flavoproteins, which are responsible both for phototropism and for regulation of the circadian clock in plants.
ANSWER: cryptochromes
[10m] Pairs of these highly reactive molecules can be produced when cryptochromes absorb blue light, as a result of electron transfer.
ANSWER: free radicals
[10e] The radical pair mechanism of magnetoreception depends on this intrinsic form of angular momentum being correlated between entangled electrons. For electrons, this quantity can be ‘up’ or ‘down’ in units of one half.
ANSWER: spin
