The enzyme that fixes carbon dioxide in the Calvin cycle is:

Answer: RuBisCO.

  • A RuBisCO
  • B amylase
  • C pepsin
  • D lipase

Correct answer: A. RuBisCO

Explanation: RuBisCO catalyses the fixation of CO₂ onto RuBP.

Photosynthesis: Inputs and OutputschloroplastLeaf cellSunlightCO2H2OO2Glucose

Simplified photosynthesis diagram: light energy, CO2, and H2O enter the leaf and are converted in the chloroplast into glucose and O2.

Concept context

Light reactions, the Calvin cycle, C 3 /C 4 /CAM pathways, photorespiration, and factors affecting the rate of photosynthesis. One of the highest-yield NEET chapters.
