  5. e 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 Multiple choice questions

  1. A photosynthetic pigment that participates directly in the light reactions, which convert solar energy to chemical energy.
  2. the synthesis of organic compounds from carbon dioxide, such as in photosynthesis
  3. 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.
  4. in chloroplasts, an acceptor of electrons lost from chlorophyll a; found in the thylakoid membrane

5 True/False questions

  1. C3 Planttype of plant that minimizes photorespiration by fixing carbon twice, using a C4 pathway in addition to the Calvin-Benson Cycle.


  2. MesophyllThe ground tissue of a leaf, sandwiched between the upper and lower epidermis and specialized for photosynthesis.


  3. photosystem IOne of two light-harvesting units of a chloroplast's thylakoid membrane; it uses the P680 reaction-center chlorophyll.


  4. spectrophotometerAn instrument that measures the proportions of light of different wavelengths absorbed and transmitted by a pigment solution.


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