Can you please help me with a simple and short answers please. Also no meed for explanation i just need answers.
Thank you
6.4 The Light Reactions and the Calvin Cycle Reactions Review the introduction to this laboratory. Note the overall equation for photosynthesis and that photosynthesis consists of the light reactions and the Calvin cycle reactions. Solar energy is absorbed by photosynthetic pigments during the light reactions and energy is used during the Calvin cycle reactions to reduce carbon dioxide to a carbohydrate. Light Reactions 1. Photosynthetic pigments a. What is the function of the photosynthetic pigments in photosynthesis? b. How does it benefit a plant to have a variety of photosynthetic pigments? (See Fig. 6.5.) c. Green light minimally promotes photosynthesis. Account for this observation with reference to the photosynthetic pigments. (See Fig. 6.5.) d. Does this explain why leaves are green? How so? 2. Water and oxygen happens to water during the light reactions? a. What b. What happens to the released oxygen? 3·Location of the light reactions membranes. Fill in the blank: The light reactions take place in the 4. In your own words, summarize the light reactions based on this laboratory Calvin Cycle Reactions 1. Carbon dioxide and carbohydrate What happens to carbon dioxide after it is taken up during the Calvin cycle reactions? 2. Location of the Calvin cycle reaction Fill in the blank: The Calvin cycle reactions take place in the 3. In your own words, summarize the Calvin cycle reactions based on this laboratory. Light Reactions and the Calvin Cycle Reactions 1. Examine the overall equation for photosynthesis and show that there is a relationship between the light reactions and the Calvin cycle reactions by drawing an arrow between the hydrogen atoms in water and the hydrogen atoms in the carbohydrate co, + H2O â (CH20) + 02 2. Only because solar energy splits water can hydrogen atoms be used to reduce carbon dioxide. In this sense, solar energy is now stored in the carbohydrate. This energy sustains all the organisms in the biosphere 6-9 Laboratory 6 Photosynthesis 73
