Calvin cycle

How is NADPH made?

*by absorbing light & using that energy to split a water molecule and transfer the electron *NADPH and ATP is made *These are then used in the Calvin cycle to produce sugar.

2 G3P=______glucose

1

CO2 is how many carbons?

1

how many free (extra) G3P do you get from 3 turns of the cycle?

1

3 steps of Calvin cycle

1. carbon fixation 2. reduction 3. regeneration

how many free (extra) G3P would you get from 1 turn of the cycle?

1/3

how many free (extra) G3P do you get from 6 turns of the cycle

2

1 G3P = ____CO2

3

3 CO2= ______ RuBP

3

G3P is how many carbons?

3

how many turns of the cycle are needed to make 1 G3P

3

how many carbons does RuBP have?

5

how many G3P are needed to regenerate 3 RuBP?

5 : so both groups have 15 carbons total

Which statement correctly describes carbon fixation? (a) the conversion of CO2 into an organic compound (b) the use of RuBisCO to form 3-PGA (c) the production of carbohydrate molecules from G3P (d) the formation of RuBP from G3P molecules (e) the use of ATP and NADPH to reduce CO2

A the conversion of CO2 into an organic compound

what is used to reduce 3 PGA?

ATP and NADPH

Where in eukaryotic cells does the Calvin cycle take place? (a) thylakoid membrane (b) thylakoid lumen (c) chloroplast stroma (d) granum

C chloroplast stroma

Which order of molecular conversions is correct for the Calvin cycle? (a) RuBP + G3P → 3-PGA → sugar (b) RuBisCO → CO2 → RuBP → G3P (c) RuBP + CO2 → [RuBisCO] 3-PGA → G3P (d) CO2 → 3-PGA → RuBP → G3P

C RuBP + CO2 → [RuBisCO] 3-PGA → G3P
