Photosynthesis

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
