PHOTOSYNTHETIC WORKSHEET а. Ware.t Light reactions Label the diagram using the word bank: NADPH NADP АТР ADP+ Р oxygen carbohydrate water. Explain the significance of each item. 1. The main photosynthetic pigments in plants аге ___ and ___. а. chlorophyll s; chlorophyll а с. retinal pigment; accessory pigment Ь. chlorophyll х; chlorophyll у d. chlorophyll а; chlorophyll Ь D 2. When а photon is absorbed Ьу а molecule, the photon а. loses its abllity to generate апу energy. Ь. raises the molecule from а ground state of low energy to ап excited state. В 3. Plants аге green because а. chlorophylls absorb Ыuе and orange-red wavelengths of light and reflect green light. Ь. chloroplasts transmit green light. с. energized chlorophyll а emits green light. d. plants do not possess green pigment. Д 4. When а photon is absorbed Ьу chlorophyll, а. the chlorophyll becomes "excited," or energized. Ь. а greater number of light wavelengths сап Ье absorbed. с Д 5. The 02 gas produced during photosynthesis is derived from а.СО2. Ь. glucose. в с с. affects the molecule in ways that are not clearly understood. d. causes а change in the velocity of the wavelengths. с. АТР is split into ADP, phosphate, and energy. d. hydrogen ions are released. с. water. d. СО. 6. Which of the following does not happen in noncyclic electron transport? с. Water donates electrons and protons. а. Oxygen gas is released. d. NADPH forms. Ь. СО2 reacts with RuBP. 7. Photosynthesis is the process that uses light energy to extract hydrogen atoms from с. water. а. glucose. d. СО2. Ь. chlorophyll. 8. ln both photosynthesis and cellular respiration, protons are pumped across а membrane during с. СО2 fixation. а. electron transport. d. reduction of 02. Ь. photolysis. А 9. А suspension of algae is incubated in а flask in the presence of both light and СО2. When it is transferred to the dark, the reduction of 3-phosphoglycerate (ЗРG) to glyceraldehyde 3-phosphate (GЗР) is Ыocked, and the concentration of ribulose 1,5- Ьisphosphate (RuBP) declines. Why does the RuBP concentration decline? с. There is а corresponding increase in RuMP. а. RuBP needs to Ье regenerated from GЗР. d. Both а and Ь Ь. Sugar is по longer generated from GЗР. А 10. Which of the following does photosynthesis and respiration have in common? с. Both require cyclic electron transport. а. ln eukaryotes, both processes occur in the mitochodrion. d. Both require light. (2_ Ь. АТР synthesis in both processes relies оп the f.) chemiosmotic mechanism.
