Question

What is one role of ATP in the light-independent reaction of photosynthesis?
ATP supplies the energy to produce glucose and other carbohydrates.
ATP is produced when water molecules are split and chlorophyll electrons are excited.
ATP supplies the energy to split water molecules.
ATP produces CO2 and O2 molecules.

Answer 1

ATP supplies the energy to produce glucose and other carbohydrates. ATP (and NADPH) from the light reactions power the Calvin cycle reactions that fix CO2 and build sugars and regenerate RuBP.
