Question

QUESTION 1

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

   organized packets of light having both a wave and particle nature part of the electromagnetic radiation spectrum which fuels photosynthesis major photosynthetic pigment which absorbs violet, red, and orange light source of carbon used to build sugars in photosynthesis part of photosystem where photon energy is converted into chemical potential energy part of photosystem where pigments funnel photon energy towards special chorophyll a molecules contains chlorophyll a called P680    contains chlorophyll a called P700 enzyme which fixes carbon during the Calvin Cycle by attaching CO2 to RuBP pathway triggered by high O2 conditions, where O2 rather than CO2 binds with the carbon fixing enzyme during the Calvin cycle - resulting in the use of ATP and NADPH without the production of glucose

   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 of photosynthesis:

   -       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 CO2 is oxidized.
   		The three major stages of the calvin cycle include: carbon fixation, reducation, and regeneration of the CO2 acceptor.
   		When an electron absorbs a photon, it goes from a ground state to an excited state.
   		Excited electrons move to higher energy orbitals and release energy as they fall back to their ground state.
   		Red wavelengths have longer wavelengths and thus lower energy.
   		Chlorophyll absorbs green light giving plants their green appearance.
   		The Calvin Cycle must turn 2 times to build up one molecule of glucose.
   		ATP is built by ATP synthase through photophosphorylation during the light reactions.

QUESTION 4

1. Choose all of the statements which describe the structure and function of the chloroplast. Hint: 2 statements are correct.

   		the chloroplast contains a fluid filled space called the stroma in which the Calvin cycle occurs facilitating photosynthesis
   		the chloroplast has photosynthetic pigments embedded in its outer membrane facilitating photosynthesis
   		the chloroplast contains thylakoids which are membranous discs in which photosystems are embedded facilitating photosynthesis
   		the chloroplast is double membrane bound allowing H+ to accumulate in the space between the inner and outer membrane of the chloroplast fueling ATP synthase
