What were the products of the light reactions to be used during the carbon reactions of photosynthesis & What was necessary to produce this?
- -Products: ATP & NADPH
- -Reactants: ADP & Pi & NADP+
Every year about 200 billion tons of CO2, are converted into biomass via [BLANK]

Photosynthesis
Carbon reactions produce [BLANK] & take place in the [BLANK]
- 1. Sucrose, Starch, Growth
- 2. Stroma
Carbon reactions occur via what process?

Calvin cycle
Definition: The reductive pentose phosphate cycle

The Calvin cycle
What are the 3 stages of the Calvin Cycle?
- 1. Carboxylation
- 2. Reduction
- 3. Regeneration
What happens during Carboxylation (STEP 1)

3 molecules of ribose-1,5 biphosphate (RuBP) are covalently bonded to CO2
Carboxylation is catalyzed by the [BLANK] enzyme?

Rubisco
Carboxylation results in [BLANK]-carbon compounds

6
What happens during Reduction (STEP 2)?

3-PGA is reduced to glyceraldehyde 3-phosphate (GA3P) using ATP & NADPH
What happens during Regeneration?
- -5 of the GA3P molecules are rearranged using ATP to regenerate RuBP
- -And the ADP produced during the reduction & regeneration phase & the NADP+ are used by light reactions to create ATP & NADPH
