Absorption of photons by the light capturing center is not directly coupled with evolving of oxygen from water. O True O False

Which of the following is not produced during the light reactions of photosynthesis?       H2O     NADPH     O2     ATP

In cyclic photophosphorylation, an electron in P700 is excited by a photon and begins to taking the same path that it took in non cyclic. True False

Which (look at figure) is an accessory pigment in red flowers?

Blue light is more effective than other colors of light in causing the phototropic response. Cryptochrome is the photoreceptor for this response. True False

Think of a metaphor or analogy of the light-dependent reactions similar to the “construction analogy”. Make sure to label your diagram and provide a ten-sentence summary that explains your analogy.

In the primary photoevent, what is excited by a photon of light? O The reaction center chlorophyll a molecule Any chlorophyll a molecule Any chlorophyll molecule O Any photosynthetic pigment molecule

Which is a difference between proteins and DNA? "Proteins contain carbon atoms, DNA does not" "DNA is found in the cell membrane, proteins are only in the cytoplasm " "DNA is mostly contained in the nucleus, proteins are found in nucleus and cytoplasm " "Proteins store information, DNA catalyzes reactions "

Melvin Calvin and Andrew Benson determined the steps in the light-independent reactions of photosynthesis by exposing the green alga Chlorella to CO2 labeled with the radioisotope carbon 14. By looking at which compounds the C14 ended up in, they were able to identify all intermediates in this cyclic pathway. Why did they predict correctly that the same set of intermediates would be formed in the light reaction in land plants?

Which color(s) of light does chlorophyll a reflect? a. red and blue b. green c. red d. blue
