Two metabolic pathways

16 ADP + 16Pi

16 ATP

12 NADP + 12H

12 NADPH

12 H2O

24 H+ + 6O2

LIGHT DEPENDENT LIGHT INDEPENDENT

LIGHT INDEPENDENT REACTION

(CALVIN-BENSON CYCLE)

1. OCCURS

STROMA

2. REQUIRES (USES)

material from

CO2 Air

ATP & NADPH Light Dependent

RIBULOSE BIPHOSPHATE (RuBP) In chloroplast

ENZYMES In membranes

RIBULOSE BIPHOSPHATE

RuBP

CO2 H2O

PGA

G3P

GLUCOSE

NAMING COMPOUNDS

1. HAVE 1 FIVE CARBON ATOMS

RuBP 5

2. ADD 1 ONE CARBON ATOM

1

3. BREAKS INTO TWO

THREE CARBON

ATOMS PGA

6

4. REARRANGES INTO TWO DIFFERENT

THREE CARBON ATOM. G3P

6

5. NEED TO REGENERATE THE

STARTING FIVE CARBON

ATOMS SO REMOVE 1

CARBON

1

COUNTING CARBONS - 1 ROTATION

6. NOT YET

1. HAVE 6 FIVE CARBON ATOMS

6 X 5 = 30

2. ADD 6 ONE CARBON ATOM

6 X 1 = 6

3. BREAKS INTO TWELVE

THREE CARBON

ATOMS

12 X 3 = 36

4. REARRANGES INTO

TWELVE DIFFERENT THREE

CARBON ATOMS.

12 X 3 = 36

5. TO REGENERATE THE

SIX STARTING FIVE

CARBON ATOMS NEED TO

REMOVE SIX CARBONS

36 – 6 = 30

COUNTING CARBONS - 6 ROTATIONS

6. GLUCOSE

ATP

ADP + P

NADPH

NADP + H
