Photosynthesis Steps Flashcards
light energy turns into ___ that is stored in plants when photo happens
biochemical energy
energy
the capacity to do work
electromagentic energy
lights form of energy
wave enrgy
where are chloroplasts found in leaves
mesophyll
where does the light rxn happen
grana, thylakoids in chloroplasts
steps of light rxn
light energy gathered in chloro
electrons become excited & break away
ADP-ATP, NADP+-NADPH (charged battery)
water molecule split (pays back chloro)
what happens when light enters the chloroplast
the electrons spin and break away, attach to ADP and NADP+ to create ATP and NADPH
uncharged battery
ADP and NADP+
charged battery
ADP and NADPH
is the water split in the light or dark rxn
light
what does the water molecule splititng release
H+ and 2 e-
photolysis
splitting of water using light energy
what happens to the 2 e- when water molecule is split
it pays back chloroplast
what is a waste product from light rxn
water
calvin cycle
dark cycle
dark cycle in general
biochemical energy used to make glucose
TF the dark cycle can hapen independently from the light rxn
F, it needs the energy from the light rxn to start the dark cycle
General process of dark cycle
CO2+NADPH+ATP
P is removed from ATP-ADP
this releases energy
H is removed from NADPH-NADP+
this releases energy
sucrose is made
Process of CO2 coming into leaf
from stomata diffused through mesophyll and parenchyma cells and then entered chloroplast
What air molecules are used to make sugar
1 C and 1/2 of O2
extra O is lost as waste product
where does P come in from atp
soil
sucrose =
glucose + fructose
