Random information moment

I’ve been tagged for a meme by Cheryl, or possibly Dianne or Laura, I think the whole blog family is tagging each other so it's getting confused. So if you're reading this...you're it.

A meme consists of any unit of cultural information, such as a practice or idea, that gets transmitted verbally or by repeated action from one mind to another. Here are the rules:1) Pick up the nearest book. 2) Open to page 123. 3) Find the fifth sentence. 4) Post the next three sentences. 5) Tag five people and acknowledge who tagged you.

Here's mine. Y'all are going to be sorry, since I'm studying for a final. This is from Biology with Physiology: Life On Earth :

Meanwhile, light rays have also been striking the pigment molecules of photosystem I (step 5 in Fig. 7-7, middle of Fig 7-8). Energy from the light photons is captured by these pigment molecules and funneled to the two reaction center chlorophyll molecules, which then eject high-energy electrons (step 6). These electons jump to the electron transport chain associated with photosystem I (step 7).

This is part of the answer to that nagging question---how do plants generate NADPH? I'm sure y'all are on pins and needles wondering what eventually happens to those high-energy electrons. Don't worry, the textbook goes on to explain they end up retiring to a small Mexican fishing village, where they run a hotel and deep-sea charter fishing service.

The End.
