QUESTION 1

1. Match each of the following with the best answer choice:

   organized packets of light having both a wave and particlenature part of the electromagnetic radiation spectrum which fuelsphotosynthesis major photosynthetic pigment which absorbs violet, red, andorange light source of carbon used to build sugars in photosynthesis part of photosystem where photon energy is converted intochemical potential energy part of photosystem where pigments funnel photon energy towardsspecial chorophyll a molecules contains chlorophyll a called P680    contains chlorophyll a called P700 enzyme which fixes carbon during the Calvin Cycle by attachingCO2 to RuBP pathway triggered by high O2 conditions, where O2 rather thanCO2 binds with the carbon fixing enzyme during the Calvin cycle -resulting in the use of ATP and NADPH without the production ofglucose

   A. photosystem I B. light harvesting complex C. CO2 D. photorespiration E. photons F. visible light G. photosystem II H. reaction center complex I. chlorophyll a J. rubisco

QUESTION 2

1. Match each of the following to the appropriate stage ofphotosynthesis:

         -       A.      B.    occurs in thylakoid of chloroplasts       -       A.      B.    occurs in stroma of chloroplasts       -       A.      B.    produces ATP       -       A.      B.    requires photosystems       -       A.      B.    requires photosynthetic pigments       -       A.      B.    builds sugar       -       A.      B.    requires rubisco       -       A.      B.    requires ETC       -       A.      B.    generates NADPH       -       A.      B.    requires RuBP       -       A.      B.    requires CO2       -       A.      B.    releases O2       -       A.      B.    breaks down H2O

   A. Calvin cycle B. light reactions

QUESTION 3

1. Choose all of the true statements below. Hint:5 statements are true.

   		In photosynthesis, H2O is reduced and CO2is oxidized.
   		The three major stages of the calvin cycle include: carbonfixation, reducation, and regeneration of the CO2 acceptor.
   		When an electron absorbs a photon, it goes from a ground stateto an excited state.
   		Excited electrons move to higher energy orbitals and releaseenergy as they fall back to their ground state.
   		Red wavelengths have longer wavelengths and thus lowerenergy.
   		Chlorophyll absorbs green light giving plants their greenappearance.
   		The Calvin Cycle must turn 2 times to build up one molecule ofglucose.
   		ATP is built by ATP synthase through photophosphorylation duringthe light reactions.

QUESTION 4

1. Choose all of the statements which describe thestructure and function of the chloroplast. Hint: 2 statements arecorrect.

   		the chloroplast contains a fluid filled space called the stromain which the Calvin cycle occurs facilitating photosynthesis
   		the chloroplast has photosynthetic pigments embedded in itsouter membrane facilitating photosynthesis
   		the chloroplast contains thylakoids which are membranous discsin which photosystems are embedded facilitating photosynthesis
   		the chloroplast is double membrane bound allowingH+ to accumulate in the space between theinner and outer membrane of the chloroplast fueling ATPsynthase
