  1. a A photosynthetic pigment that participates directly in the light reactions, which convert solar energy to chemical energy.
  2. b green pigment in plants that absorbs light energy used to carry out photosynthesis
  3. c A plant that uses the Calvin cycle for the initial steps that incorporate CO2 into organic material, forming a three-carbon compound as the first stable intermediate.
  4. d reactions of photosynthesis that use energy from light to produce ATP and NADPH
  5. e organism that obtains energy from the foods it consumes; also called a consumer

5 Multiple choice questions

  1. The fluid of the chloroplast surrounding the thylakoid membrane.
  2. almost identical to chlorophyll a, but slightly different absorption spectra, yellow-green
  3. reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars
  4. The process of generating ATP from ADP and phosphate by means of a proton-motive force generated by the thylakoid membrane of the chloroplast during the light reactions of photosynthesis.
  5. a 3 carbon sugar; for each CO2 are formed in the Calvin cycle; 1 leaves to be used in the cell, 5 are use for regeneration of RuBP
