Photosynthesis, page 13

Here is the latest page for the photosynthesis story. I predict only 4-5 more pages to go! I need to get close by the time classes start on the 17th because this year in Comics and Culture we are making the students write and draw a 2-4 page comic explaining an idea or concept form the major. I hope to use this story as an example of the process.

It has been added to the rest of the story which has been archived in the Whole Enchilada post.

  1. Hey Jay,

    unfortunately the ATP Synthase needs 14 Protons to make 3 ATPs. It has (unlike other ATPases of bacteria and so on) 14 membrane-integrated c-subunits.

    Look here, Wolfgang Junge found out in 2005

  2. Thanks, Martin! That is an easy fix to make. I’ve been working out of a few (relatively new) cell biology texts and they clearly aren’t as current as they could be. And I really appreciate the reference!

  3. Argh, I’m sorry. I digged through my papers library and found out, it was not Wolfgang Junge, but Holger Seelert who found out – already in 2000! The paper I was referring to is just a review by Junge …

    Seelert in 2000:

    We have imaged the ATP synthase from leaf chloroplasts by using atomic force microscopy and, surprisingly, find that its turbine has 14 subunits, arranged in a cylindrical ring.

  4. Hi Heather,The Elementary Chemistry Book Bundle includes a print stdunet text (ST), teacher’s manual (TM), and laboratory workbook (LW), and downloadable lesson plan.Here are some suggested sequences:Sequence 1 – Begin in Grade KGrade K- Pre-Level I Chemistry Grade 1- Pre-Level I BiologyGrade 2- Pre-Level I PhysicsGrade 3- Pre-Level I Geology/Astronomy (coming Fall 2010)Grade 4 – Level I Chemistry + KogsGrade 5- Level I BiologyGrade 6- Level I PhysicsGrade 7- Level I Geology/Astronomy (coming Fall 2010)Grade 8- Level 2 ChemistryGrade 9- ready for high school scienceI surely recommend the Level 1 for your 5,7, and 10 years old as well. At this age kids are ready to start learning the basic steps of the scientific method. The Elementary (Pre-Level I) series presents complex science concepts in language readily understood by young children. There are an abundance of colorful illustrations and graphics throughout the text that also help make the material engaging and memorable! In addition If you child does not yet read, read the text book to them and then have an oral discussion to the text,also hands-on experiments connect the concepts to real life, making the lessons really stick.If you have any question or concerns please let me know.
