|
In light-dependent reactions, light shines on the molecule called?
|
Chlorophyll
|
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
|
glucose
|
|
|
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
|
CC
|
|
|
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
|
add
|
|
|
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 ..?
|
NADP+
|
|
|
|
dark reactions happen in the ?
|
Stroma .. outside chloroplast
|
|
|
|
NATP picks up
|
hydrogen from breaking water!
|
|
|
|
Light energy is converted to?
|
Chemical energy and stored
|
|
|
|
Photolysis:
|
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
