  • 3rd side (hint)
In light-dependent reactions, light shines on the molecule called?
In plants
The light shining on the molecule chlorophyll causes electrons to gain --- and -----
Gain energy and leave the chlorophyll
Gain (sunlight) and exit
6CO2 + 6H2O + light energy =
C6H12O6 + 6O2
Divided into 2 sets of reactions named
Light and Dark reactions
In sun and out of sun
What is required for photosynthesis?
Chloroplast struture, chlorophyll, light energy, CO2, and H2O
There are 5.
Photosynthesis produces?
PGAL later to 2 PGAL && the waste product O2
Glucose && waste
Light reactions 1st two steps are?
1.Light captured by chloropyhll, loses electrons 2. Water is split to replace electrons; O2 released (waste)
Light && waste
Third steps of light reactions?
3.Electron energy is transferred to ADP+P + e-energy --> ATP other electron energy + H+s go to NADP+ --> NADPH
Sunlight transfer
4th step of light reactions
ATP && NADPH represent light energy in the form of chemical energy; provide E in dark reaction
The first step of Dark reactions?
CO2 is taken in, fed into Calvin Cycle
2nd step of dark reactions?
CO2 is combined with 5-C sugar by enzyme Rubisco; makes temporary 6-C compund; breaks down to 3-C sugars (PGA); changed to 2PGAL
Carbon compounds
3rd step of dark reactions?
3X around the cycle; put in 3CO2; make one net PGAL (simple 3-C sugar)
times round circle
4th step of dark reactions?
since 3 CO2 has less energy than PGAL; must add energy (ATP && NADPH) from light reactions
Last step of dark reactions?
Add 2PGAL into later reactions (glucose)
Photosynthesis takes place in the..?
Thaykloid membrame
As electrons go down the transport chain they.. energy?
lose energy, used to make ATP
electrons combine with ..?
dark reactions happen in the ?
Stroma .. outside chloroplast
NATP picks up
hydrogen from breaking water!
Light energy is converted to?
Chemical energy and stored
1. H2O is split (hydro-energy source for Calvin) 2. O2 is given off
Chlorophyll A? B? Xanthophyll? Carotemes? Antho Eayanim?
A. Bright Green B. Yeller Green Xan. Yellow Caro. Faint Yellow Anth. Red
First pigment to break down in fall?
Chlorophyll A
Adenosine Triphosphate .. Adenosine Diphosphate.. Adenosine Monophosphate
Chlorophyll stacked like ??
nicotinamide adenine dinucleotide phospate
4H+ + O2 + 4e-
5-carbon sugar
ribulose biphosphate (RuBP)
phophoglyceric acid
PGA to PGAL ..
Calvin cycle named after .?
Melvin Calvin
