Lecture 12

Photosynthesis

April 24, 2025

Questions

1What are the two main stages of photosynthesis?

2Where in the chloroplast does each stage occur?

3What is the role of ATP and NADPH?

4How do light-dependent reactions produce O2?

5What factors affect the rate of photosynthesis?

Notes

Key Idea 1 Two main stages: Light-dependent reactions and Calvin cycle.

Key Idea 2 Light-dependent reactions capture light energy, split H2O, and produce ATP and NADPH.

Key Idea 3 Calvin cycle uses ATP and NADPH to fix CO2 and produce sugars.

Key Idea 4 Rate depends on light intensity, CO2 concentration, temperature, and water availability.

Summary

Photosynthesis converts light energy into chemical energy. Light reactions make ATP and NADPH. Calvin cycle uses them to build sugars.
