Photosynthesis (video) | Cellular energetics | Khan Academy
Photosynthesis involves two stages: the light-dependent reactions, which require sunlight and water to produce oxygen, ATP, and NADPH, and the light-independent reactions (or "dark …
Breaking down photosynthesis stages (video) | Khan Academy
Light-dependent reactions use light energy and water to produce ATP, NADPH, and oxygen. Light-independent reactions then uses ATP, NADPH, and carbon dioxide to create sugar. This …

We know plants make their food by photosynthesis, but did you know that photosynthesis is not a simple reaction? Watch this video to learn more about the first step in photosynthesis, the light …
An introduction to photosynthesis (article) | Khan Academy
The light-dependent and light-independent reactions work together to capture the energy from sunlight and convert it into chemical energy in carbohydrates. The light-dependent reactions …
