  1. a a tiny particle or packet of light energy
  2. b process by which plants use the sun's energy to convert water and carbon dioxide into sugars
  3. c type of plant that minimizes photorespiration by fixing carbon twice, using a C4 pathway in addition to the Calvin-Benson Cycle.
  4. d the synthesis of organic compounds from carbon dioxide, such as in photosynthesis
  5. e An instrument that measures the proportions of light of different wavelengths absorbed and transmitted by a pigment solution.

5 Multiple Choice Questions

  1. green pigment in plants that absorbs light energy used to carry out photosynthesis
  2. One of two light-harvesting units of a chloroplast's thylakoid membrane; it uses the P680 reaction-center chlorophyll.
  3. in chloroplasts, an acceptor of electrons lost from chlorophyll a; found in the thylakoid membrane
  4. that portion of the electromagnetic spectrum detected as various colors by the human eye, ranging in wavelength from about 380 nm to about 750 nm.
  5. 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 True/False Questions

  1. photosystem IOne of two light-harvesting units of a chloroplast's thylakoid membrane; it uses the P700 reaction-center chlorophyll.

          

  2. Light Reactionsorganism that obtains energy from the foods it consumes; also called a consumer

          

  3. PEP CarboxylaseAn enzyme that adds CO2 to phosphoenolpyruvate (PEP) to form oxaloacetate in C4 plants. It acts prior to photosynthesis.

          

  4. NADPone of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules

          

  5. G3Pa 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
