Plants turn light into chemical energy in two stages. The first captures energy from light; the second spends it to build sugar from CO₂.
Light-dependent reactions 04:12
- Happen in the thylakoid membranes
- Water is split and oxygen is released as a by-product
- Energy is stored as ATP and NADPH
The Calvin cycle 17:40
- Runs in the stroma and needs no light directly
- RuBisCO fixes CO₂ into three-carbon sugars
Stop wasting time controlling playback.
LunaNotes auto-extracts and organizes the entire video so you never need to pause, rewind or jump around again.
Transcript
Search ⌘KSo the light reactions leave us with two things: ATP and NADPH.
Neither of them is sugar yet. That's what the second stage is for.
The Calvin cycle runs in the stroma, and it doesn't need light directly.
Its key enzyme, RuBisCO, grabs CO₂ from the air and attaches it to a five-carbon sugar.
The result splits into two three-carbon molecules, and that's where glucose starts.
RuBisCO is slow, which is why plants make so much of it.
No more unformatted auto-captions.

Why plants need light
Photosynthesis turns light energy into chemical energy stored in glucose.

Light-dependent reactions
In the thylakoids, water is split, oxygen is released and ATP and NADPH are made.

The Calvin cycle
In the stroma, RuBisCO fixes CO₂ into three-carbon sugars using ATP and NADPH.

Frequently asked questions
Paste any YouTube link into LunaNotes and the system will extract the transcript, generate summaries, add timestamps, and give you organized notes instantly. It’s the fastest way to turn youtube to notes without manual work.
Yes, LunaNotes works with any public YouTube video including lectures, tutorials, explainers, coding sessions, interviews and more. If the video is available to watch publicly, you can convert that YouTube video to notes instantly.
If a video has no captions, LunaNotes attempts to extract the audio and process it directly. Accuracy may vary depending on audio quality, but you will still receive structured notes and timestamps.
You get 1,000 free AI credits every month. Each AI action is charged for what the model actually used; a typical video summary on the default model is about 25–50 credits. That covers the YouTube link to notes workflow for most people on the free plan.
No, LunaNotes works on the web. The Chrome extension simply makes it faster — letting you convert a YouTube video to notes directly from the video page.
