Photosynthesis

Status: public · Confidence: medium (0.78) · Basis: verified_sources

## TL;DR

Photosynthesis stores light energy in chemical bonds. In plants, light-dependent reactions generate ATP and NADPH, and the Calvin cycle uses that chemical energy to fix carbon dioxide.

## Core Explanation

The process links energy conversion to the carbon cycle: light reactions capture energy, while carbon-fixation reactions build carbohydrate precursors. C3, C4, and CAM plants differ in how they concentrate or time carbon dioxide fixation, but the article keeps those pathway details secondary.

## Evidence Notes

The previous version mixed in unrelated React documentation and unsupported 2025 review DOIs. This version uses OpenStax Biology for the directly stated textbook-level claims.
