Final answer:
Photosynthesis occurs in two stages: light-dependent reactions and the Calvin cycle. In the light-dependent reactions, chlorophyll absorbs energy from sunlight and converts it into ATP and NADPH, while water is split and oxygen is released. In the Calvin cycle, ATP and NADPH are used to convert carbon dioxide into glucose.
Step-by-step explanation:
Photosynthesis occurs in two stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, chlorophyll absorbs energy from sunlight and converts it into chemical energy, producing ATP and NADPH. Water is split, releasing oxygen as a byproduct. In the Calvin cycle, ATP and NADPH are used to convert carbon dioxide into glucose.
