Below are sample questions representative of the exercises included on this worksheet and related 10.40 Calvin Cycle and Carbon Fixation skill assessments:

Problem 1Difficulty: Mastery

Which statement best synthesizes the relationship between the light reactions and the Calvin cycle?

ALight reactions make CO2, and the Calvin cycle splits CO2 to release oxygen gas.

BThe Calvin cycle makes photons, and light reactions use photons to build RuBP from glucose.

CLight reactions convert light energy into ATP and NADPH, and the Calvin cycle uses them to fix CO2 into sugar precursors.

DBoth stages occur in mitochondria and release ATP by breaking down G3P.

Solution & Explanation:The two stages are linked: light reactions provide ATP and NADPH, while the Calvin cycle uses those carriers to incorporate CO2 into carbohydrate precursors.

Problem 2Difficulty: Mastery

Use the three-plant data table. Which plant most likely has a CO2-concentrating adaptation supporting the Calvin cycle under dry conditions?

APlant Q, because it maintains high fixation with low stomatal conductance

BPlant P, because it has high conductance but low fixation

CPlant R, because it has low fixation and low internal CO2

DAll three equally, because conductance and fixation are unrelated

Solution & Explanation:A plant that maintains relatively high fixation while stomata are less open may be concentrating CO2 internally or using a water-saving carbon fixation strategy.

Problem 3Difficulty: Mastery

If RuBisCO binds oxygen instead of carbon dioxide more often, what is the best prediction for fixed-carbon efficiency?

AEfficiency increases because oxygen contains carbon for sugar formation.

BEfficiency stays identical because RuBisCO reactions never affect carbon flow.

CEfficiency increases because ATP is no longer needed for G3P formation.

DEfficiency decreases because more energy is spent recovering from photorespiration.

Solution & Explanation:Oxygenation by RuBisCO starts photorespiration, which uses energy and can release CO2, lowering efficient carbon gain.
