reduced
What does NADP take to go to NADPH
electron and proton
What is lost e energy in I used for?
to combine e, proton, and NADP to form NADPH

NADP
enter ETC, then return to PSI
cyclic photophosphorylation
when might cyclic occur
high light intensity/sunlight
process making aTP

1
5
how many turns to make 1 glucose
6
where do pgal’s meet
cytoplasm
Reflect red and blue
antocyanins
Why called c3
first intermediate formed = pga
why do c3 respirate
hot and close stomata
c3 must spend additional energy to fix __ in molecules
02
how much sugar prod drop
50
Why called c4
makes 4 c compound that goes to CB cycle
Sugar cane, corn, and crabgrass are
c4
c4
where is carbon first fized
mesophyll cells, then co2 released to be fixed in bundle-sheath cells with normal CB cycle
Loses less water than the others
CAM
cacti, pineapples succulents are
CAM
In CAM, the co2 taken in at night is realized when
during the day the it goes to traditional CB cycle
when CO2 is first incorporated into 4 c organic compound
c4
What plateaus
light increases, and co2 increases
temperature
increase, then denature and stomata close
Why do they plateau
special pairs already excited
synthesis of ATP
chemiosmosis
If it says cyclic, it is referring to
CB cycle

coenzyme
CAM makes
malic acid
