The Vision Thing

(to the tune of “Star Spangled Banner”)

Copyright © 2012 Kevin Ahern

David Simmons' recording HERE


Did you know you can see

In the dimmest of light

With your rods and your cones

And their retinaldehyde


Found in rhodopsin it’s

Got a bond shaped as cis

But it changes its state

When a photon gets it straight


Then the sign’ling kicks in

Thanks to a transducin

Cuz its GTP ways

Turn on diesterase


So gated ion channels stop

Charges from passing through

Such as sod-i-um plus one

And cal-ci-um plus two
