Photosynthesis
|
Light NRG converted into glucose (chemical NRG)
6 CO2+ 12 H2O + Light = C6 H12 O6 + 6 H2O and 6 O2 Reduction reaction, the C of the CO2 is gaining electrons from the Water Light independent and Light Dependent Both req light! |
|
|
Autotroph
|
organisms that make their own food
|
|
|
Light
|
Reflected, Transmitted, or Absorbed
If green, reflects green light and absorbs all other colors |
|
|
Light-dependent Reaction
|
Occur in Grana of Chloroplasts, more specifically the Thylakoids.
|
|
|
Thylakoids
|
Contain thousands of photosystems
|
|
|
Photosystems
|
Contain chlorophyll a, and accessory chlorophyll b and carotenoids.
Large amounts of ATP produced |

|
|
Light-independent Reaction
|
Occur in the stroma, Produce sugar.
|
|
|
Carbon fixation
|
carbon dioxide into sugar
|
|
|
Calvin Cycle
|
Requires large amounts of ATP, ATP from light dependent reaction.
|
|
|
Rubisco (ribulose biphosphate)
|
Enzyme req. for Calvin cycle
|
|
|
Cell Respiration
|
Occurs all the time
Oxidation reactions In mitochondria Needs ETC for proton gradient Needs O2, expels CO2 NAD is proton carrier ATP produced by ATP synthase Krebs Cycle |
|
|
Photosynthesis
|
Only in light
Reduction reactions occurs in chlorplasts needs ETC for proton gradient NEEDS CO2, produces O2 NADP is proton carrier ATP synthesized by ATP synthase Calvin Cycle |
|
|
Epidermis
|
Clear, does not carry out photosynthesis, protects underlying cells
Cutin, waterproof layer to minimize excess water loss. |
|
|
Guard Cells
|
Control closing of stomates.
|
|
|
Stomates
|
Control gas exchange with minimal water loss
|
|
|
C-4 Photosynthesis
|
modified anatomy and biochemical pathways. Minimize water loss and maximize sugar production
These plants thrive in hot sunny enviros where other plants would die Corn, sugarcane, crabgrass |
|
|
NADPH
|
carries H+ from grana to stroma for calvin cycle
|
|
|
PGAL
|
Phosphoglyceraldehyde (3 Carbon Sugar)
|
|
|
Photolysis
|
Splitting apart of H2O during light dependent reaction
electrons replace lost by chlorophyll a and protons for production of sugar Oxygen is released into the environment |
