Using a microscope, a student notices a small green organelle inside a plant cell. Which of the following is most likely to happen first in this organelle?

Hydrogen ions diffuse across a membrane and ATP is produced.
Light-independent reactions absorb carbon dioxide to make larger organic molecules.
The Calvin cycle produces oxygen as a waste gas.
Light-dependent reactions absorb sunlight and transfer the energy to electrons.
