light independent reaction

which parts of the photosynthesis equation ( light dependent reaction ) remain unaccounted for ?

H2O → split of water in photolysis

O2 → Released as waste product

what are the products of light dependent reaction that will be used in the Calvin cycle.

NADPH and ATP

what is ATP made from ?

ADP + inorganic phosphate molecule

what is the main purpose of the Calvin cycle ? 

To convert CO2 in the atmosphere  to carbohydrates ( sugars ) 

where does the light independent reaction take place ?

in the stroma of the chloroplast

what are the 3 phases of the light independent reaction ?

1) CO2 fixation

2) CO2 reduction 

3) Regeneration of RuBP 

how many carbons are in RuBP molecule ?

5

what is the name of the enzyme involved in capturing carbon from the atmosphere ?

Rubisco

why does 6-c molecule split ?

The 6-c molecule is unstable so the molecule split into 2 × 3-c molecules.

what products from the light dependent reaction are used in the light independent reaction ? 

ATP and NADPH ( reduced NADP ) 

what stage are the products used in ?

CO2 reduction

how many cycles of the light independent reaction are required to form 1 glucose molecule ? 

6 cycles 

can the light independent reaction occur without the light dependent reaction ? 

No it needs the NADPH and ATP from light dependent reaction to proceed. 

Stage 1 CO2 fixation

CO2 ( 1c ) → 6-C via Rubisco capturing carbon from atomsphere

6C → 2 × 3-C molecule called “ GP “

Stage 2 CO2 reduction

2× 3-c molecule “ GP “ → 2 × 3-c called " TP”  via (NADPH and ATP) from the light dependent reaction  → (ADP + Pi ) + ( NADP + ) 

NADP is oxidised , carbon compound is reduced. 

stage 3 regeneration of RuBP

2 × 3-c called " TP” →

1) 1-C from “ TP “ used to make C6H12O6 * cycle must occur 6x time to produced Glucose

2) 2 × 3-c → RuBP ( 5-c ) via ATP used via ADP + Pi
