5 Matching questions

  1. Chlorophyll b
  2. PEP Carboxylase
  3. heterotroph
  4. photosystem I
  5. photophosphorylation
  1. a 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.
  2. b organism that obtains energy from the foods it consumes; also called a consumer
  3. c almost identical to chlorophyll a, but slightly different absorption spectra, yellow-green
  4. d One of two light-harvesting units of a chloroplast's thylakoid membrane; it uses the P700 reaction-center chlorophyll.
  5. e An enzyme that adds CO2 to phosphoenolpyruvate (PEP) to form oxaloacetate in C4 plants. It acts prior to photosynthesis.

5 Multiple choice questions

  1. process by which plants use the sun's energy to convert water and carbon dioxide into sugars
  2. A route of electron flow during the light reactions of photosynthesis that involves only photosystem I and that produces ATP but not NADPH or oxygen
  3. 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
  4. The distance between crests of electromagnetic waves.
  5. A photosynthetic pigment that participates directly in the light reactions, which convert solar energy to chemical energy.

5 True/False questions

  1. visible lightThe distance between crests of electromagnetic waves.

          

  2. Chlorophyllgreen pigment in plants that absorbs light energy used to carry out photosynthesis

          

  3. Carbon fixationthe synthesis of organic compounds from carbon dioxide, such as in photosynthesis

          

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

          

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