I Need a Little Light (The Photosynthesis Song)


I need a little light
So I can store energy
I need a little light
So I can make ATP
I need a little light
I’m gonna make some food
It’s outta sight
And I need a little light

Been sittin here in this chloroplast, feeling green the whole day through
Yeah, I’m a little thylakoid, waitin for something to do
I’m gonna move some electrons through a chain
That’s gonna pump some hydrogen in
But it’s been dark all night and you can see the state I’m in

CHORUS

When the electrons leave the chain they’re gonna join NADP (plus)
And that high conconcentration of hydrogen’s gonna want outside of me
Gonna go through a special protein that’s gonna kick some ATP out
That’s what movin these electrons is really all about

CHORUS

The ATP and NADPH are gonna make a cycle go round
At the end of the calvin cycle glucose can be found
You gotta put in 6 pieces of CO2 to make that precious food
And use up the products of the thylakoid, darn this system’s good

CHORUS

The chlorophyl that lost the electrons is gonna have to get some more
So an enzymes gonna break apart water (using 6 no less no more)
It’s gonna produce 6 molecules of fresh O2, though the plant just thinks it’s waste
It’s amazing to think that this photosynthesis is happening all over the place
