Photosynthesis: Chemiosmosis (Chloroplast vs. Mitochondria)

Mitochondria:

- electrons from organic substances
- chemical energy transferred to ATP
- electrons pumped from matrix to inner membrane space
- ATP goes into matrix

Chloroplast:

- electrons from water
- light energy transferred to ATP
- protons pumped from stroma to lumen (thylakoid space)
- ATP goes into stroma
