05.L BIO, HN Comparing Photosynthesis & Cellular Respiration (PART L)

Photosynthesis (Chemiosmosis/Pumping of H+)

In chloroplasts, protons are pumped into the thylakoid space and drive ATP synthesis as the H+ ions diffuse back into the stroma

Cellular Respiration (Chemiosmosis/Pumping of H+)

In mitochondria, protons are pumped to the intermembrane space and drive ATP synthesis as the H+ ions diffuse back into the mitochondrial matrix
