Answer:
Carbon fixation
Explanation:
In this reaction, carbon dioxide reacts with hydrogen ions formed during the light stage to form glucose.This is a complex process involving several enzyme-catalyzed reactions. The process requires energy which is provided by the ATP formed during the light reactions.
Plants use energy from sunlight to turn water and carbon dioxide from what they get into an energy-rich sugar called glucose. This process is called photosynthesis, which means “making things with light”. In photosynthesis, the energy in light is absorbed by photopigments.
