  1. CELLULAR ENERGETICS PHOTOSYNTHESIS

  2. FORMULA 6CO2 + 6H2O  C6H12O6 + 6O2 carbon dioxide + water  glucose + oxygen http://www.grographics.com/risd/DmInfoBreath/1st-install/images/infobreath-mark.jpg http://extension.missouri.edu/xplor/agguides/hort/g06021.htm http://library.thinkquest.org/C004535/media/pea_leaf_stomata.gif http://www.hightechlandscapes.com/hightechlandscapes/images/watering_plants.jpg

  3. The Formula Is Not Enough (again…) • Photosynthesis is broken down into 2 major stages. Each stage again occurs in a series of enzyme-controlled reactions: • Light Dependent Reactions • Light Independent Reactions (formerly known as “Dark Reactions”)

  4. The Chloroplast http://www.ualr.edu/botany/chloroplast.jpg

  5. Light Reactions • Require light directly (uuhhh…..) • Photons of visible light excite chlorophyll molecules in the grana ROYGBIV • Light wavelengths primarily used by plants are R andBI • They do not use G since this is reflected

  6. Light Reactions 6CO2 + 6H2O  C6H12O6 + 6O2 • Water gets split • Oxygen is either used in respiration or gets released through stomata • H+ is used to make ATP and NADPH • Photosystem II – splits H2O to produce O2 • ETC produces ATP • Photosystem I – uses H+ to produce NADPH

  9. Light Independent Reactions 6CO2+ 6H2O C6H12O6 + 6O2 • CO2 enters through stomata • CO2, NADPH & ATP enter Calvin Cycle • Glucose is produced

  10. Photosynthesis ProseAdapted from PBS.org Photosynthesis, the trapper of light;     it's needed for life to exist. Plants use the process to make food;     without it most life would desist. The process begins with plain water     but not from the tap does it flow. Some water is made within leaf cells     and some is sucked up from below.

  11. With energy gained from sunlight,     the Hs are stripped from each O. The oxygen atoms form twosomes,     and out of the leaf they all go. Meanwhile CO2 has just entered     through holes in the leaf called stomata. The gas is exhaled by Earth's creatures,     including all vertebrata.

  12. But the plant has a goal that is bigger in scope;     it's out to make food it can keep. It builds a big structure with C, H, and O;     it's glucose, and boy is it sweet. Some folks get a kick from equations,     which explain things by some kind of law. If by chance you are one of these people,     then this explains what you just saw-6CO2 + 6H2O  C6H12O6 + 6O2

  13. I Will Follow You into the Dark Reaction NADPH, you, me and ATP We have found this time, time to go into the dark Reactions of photosynthesis We should not whine about this Because we are sustaining life (chorus) We can’t forget about our friend H2O We lost him long ago … In photosystem II You see it’s okay though, we used his hydrogen And that’s how we got to you, NADPH (chorus) Chorus: When CO2 arrives we will all be satisfied We’ll pack up all our bags and we’ll have a good time Heading to the stroma to produce some glucose You’ll be recycled because you’ve done your part The Logan White Experience featuring the Vocal Stylings of Chris Mattson And Co2 I’ m so lucky to have you You probably were exhaled by a random passerby You entered through the stomata, I’m so glad that I got ya Because of carbon fixation You see you have made my job possible (chorus)
