This is a list of some of the steps in the process of seeing aflash of light. Put them in cause-and-effect order from first tolast.
A. Photons pass through the ganglion and bipolar cells in theretina
B. Phosphodiesterases break down cyclic GMP
C. A photon is absorbed by a retinal molecule
D. The rod is hyperpolarized
E. Photons are refracted by the lens
F. Transducin molecules bind GTP
G. cGMP-gated Na+ channels close
H. Rhodopsin changes shape to its active conformation
I. Photons pass through the cornea
J. Transducin molecules activate phosphodiesterases
