Description

Photosynthesis Worksheet: Calvin Cycle 1) Carbon enter as CO2 and leaves as sugar. 2) ATP supplies the energy for the Calvin Cycle. 3) 3 molecules of CO2 are needed to net one molecule of G3P. 4) G3P is used to create glucose. 5) The 3 Phases of the Calvin Cycle: 1. Carbon fixation 2. Reduction 3. Regeneration of the CO2 acceptor (RuBP). 6) CO2 reactants with ribulose bisphosphate (RuBP), catalyzes by the enzyme rubisco. The reactants of this reaction are not organic. 7) NADH is the reducing agent that helps form six G3P 8) Two G3P is used to form glucose. 9) The reaming G3P are used to regenerate RUBP. Three atp molecules are used. 10) Nine ATP and six molecules of NADPH are used to create one net G3P. 11) Hot arid climate have driven the evolution of alternative pathways of carbon fixation. 12) The problem for these plants is on hot dry days less sugar is produced, because the plant must keep its stomata closed to conserve water. 13) Plants in hot dry days close their stomata in order to conserve water, however, this does not allow for CO2 to go in. More so, the enzyme rubisco can bind O2 in place of CO2 which cause the oxidation or breakdown of RuBP. 14) C4 plants have two kind of photosynthetic cells: bundle-sheath cells and mesophyll cells. The bundle-sheath cells are grouped round the leaf’s veins, and the mesophyll cells are dispersed elsewhere around the leaf. 15) C4 plants are named C4 because they form the four carbon compound oxaloacetate. 16) The four carbon compound oxaloacetate is formed in the mesophyll cell. It shipped to the bundle-sheath cell. When it get their CO2 is released and a Pyruvate is created. 17) The CO2 is released 18) The advantage of a high CO2 concentration is so that rubisco will be more likely to bind to CO2 rather than O2. 19) CAM plants prevent water loss by closing their stomata during the day. 20) At night the stomata is open and CO2 enter the plant.

21) In C4 plants and CAM plant CO2 is first transformed into an organic intermediate before it enters the Calvin Cycle. 22) In C3, C4, and CAM plant all use the Calvin Cycle, they just have different method for getting their....
