Building Vocabulary: Plant Adaptations to Hot, Dry Climates 6 of C3 photosynthesis photorespiration 1. In plants, the first product of carbon fixation is the three-carbon compound 3-PGA formed in the Calvin cycle 2. When such plants close their stomata on hot, dry days to conserve water leaf and is added to RuBP in place of CO2 A two-carbon product of this reaction is broken down to Co2 consuming ATP and generating no sugar 3.

An extremely important process is called "CARBON FIXATION' What is carbon fixation? This is where plants incorporate CO_2 into organic compounds-the base of our food web This is where plants strip electrons from organic food molecules This is the stage in photosynthesis where glucose appears This is the stage in Calvin cycle where ribulose bisphosphate is regenerated, ready for a new cycle This is where photosynthetic species are eaten, moving their energy into the food web Plants couple tow photosystems...

1)Now, the issue of the effect of carbon dioxide (carbon) is one that is hotly debated. You will find scientific arguments that indicate things are actually worse than the science-based models predict. And, you will find arguments that indicate the opposite. Some of these may not be well supported by science and thus do not hold up under careful scientific scrutiny. Indeed, there is some thought that even if we were to eliminate most people-induced carbon emissions promptly, Earth would...
