6co2 + 12h2o + light 6o2 + c6h12o6+ 6h2o. Convert 2 low energy molecules into a high energy molecule. Light energy is used to make chemical energy. The calvin cycle (dark reactions) occurs in the: Thylakoids are stacked to form a granum which are all suspended in the stroma. A collection of several hundred pigment molecules in thylakoid membrane. Special versions of chlorophyll a ( p700 or p680) In order to pick up a wide range of light to generate energy. H2o photosystem 2 cytochrome complex photosystem 1 nadph calvin cycle (dark rxns) Where did most of the mass (dry weight) of this tree come from: air. Parent molecule separation of strands daughter dna molecules each consisting of one parental strand and one new strand. Which of the following dna backbones complement to: 3"aggtcctac: 5" tccaggatg. Helicase (does the untwisting) topoisomerases (deals with the unwinding problem) Single strand binding proteins (these hold the two strands apart when they bond. )
