What are the products of the light reactions in photosynthesis? ATP, NADPH₂ and oxygen ATP, PGA and NADH₂ ATP and NADP ATP, PGA and oxygenQuestion 1 of 10Question 2 of 10 2. Photo respiration takes place only in All cells of the plant Mitochondria Green parts of the plant Root Question 2 of 10Question 3 of 10 3. In C₄ plants, fixation of CO₂ occurs in Cortex of stem Phloem tissuePalisade tissue Spongy mesophyll and bundle of sheath Question 3 of 10Question 4 of 10 4. During dark reactions the three carbon atoms of 3-PGA are derived from CO₂ only RuBP + CO₂ + PEPRuBP + CO₂ RuBP only Question 4 of 10Question 5 of 10 5. In C₃ plants first stable product of photosynthesis during dark reaction is: PGAL RuBP OxaloacetatePGA Question 5 of 10Question 6 of 10 6. Removal of the source of carbon dioxide from photosynthesizing chloroplasts results in rapid changes in the concentration of certain chemicals. Which one of the following represents the correct combination of concentration changes? ATPRibulose bishposphate Phosphoglyceric acid (PGA)ADecreases Decreases Increases BDecreases Increases No change CIncreases Increases Decreases DIncreases No change Increases ADBCQuestion 6 of 10Question 7 of 10 7. During the light dependent stage of photosynthesis, the photo activated pigment removes an electron from the hydroxylation derived from the water molecule. The fate of the free hydroxyl radical is that it:Reduces carbon dioxide to sugar Is used to produce adenosine triphosphate from adenosine diphosphate Is broken down into oxygen and a free radical of hydrogen Is used to raise the activation level of chlorophyll by donating positive charge Question 7 of 10Question 8 of 10 8. Chlorophyll is soluble in Organic solvent Water and organic solvent Not in any solvent Water Question 8 of 10Question 9 of 10 9. ATP synthesis during light reactions is Photolysis Substrate phosphorylation Oxidative Photophosphoryation Question 9 of 10Question 10 of 10 10. Carbon dioxide labeled with ¹⁴C has been used to identify the intermediate compounds in the Calvin cycle, the light-independent stage in photosynthesis. Which compound would be the first to contain the ¹⁴C? Glucose RuBPStarch PGA Question 10 of 10 Loading...
