what is the equation for photosynthesis
CO2+H2O+sunlight——>O2+C6H12O6
what is the goal of photosynthesis
to turn light energy into chemical potential energy in glucose
where do the reactants of photosynthesis come into the leaf
CO2 - stoma
H2O - central vein
sunlight - shines onto leaf (cuticle/top of leaf) eventually goes to chloroplast
where do the products of photosynthesis leave the leaf
O2 - stoma
C6H12O6 - central vein (goes to other parts of the plant)
Where does the oxygen released by plants originally come from?
the water (H2O)
Is glucose made during the light dependent reactions?
no
What is the goal of light dependent reactions?
To convert sunlight into NADPH and ATP for the light independent reactions
What role are NADPH and ATP serving within the chloroplast?
They are shuttling energy and hydrogens from light reactions to the Calvin Cycle
what is the order of structures/ reactions that occur in LDR
PSII - ETC - PSI - ATP Synthase
where the the LDR occur
the membrane of the thylakoid
where do LIR occur
stroma
what is the name for the inside of the thylakoid
lumen
where does the Calvin cycle occur
stroma
what is carbon fixation
first part of the calvin cycle - takes inorganic carbona nd turns it organic with rubisco
what is rubisco
an enzyme that speeds up carbon fixation
what does carbon fixation make
G3P (C3H5O3P)
how does GP3 become half a glucose
it is converted to add an H and remove the P
how many cycles of the calvin cycle need to happen to make glucose
2
how many CO2 molecules are needed in the calvin cycle to make glucose
6
why is high heat bad for plants
the water in the plant will evaporate through the stoma
why can thte plant just close there stoma and do the all the phtotsynthesis they can and wait to release the O2
if there is too much O2 in a plant (since it is a product of photosynthesis) rubisco is stupid and will try to use O2 to “make glucose” which doesnt work obviously (this is called transperation)
what do C4 plants do
separate the O2 from the rubisco and calvin cycle area
what do CAM plants do (cacti)
do the reactions at different time of day
what are C3 plants
plants that are regular in which they can’t survive in high heat climates
