The electrochemical gradient in a chloroplast can have a concentration of protons 1000 times greater on one side of a thylakoid membrane than the other. a. true b. false

The statement above is TRUE.
The electrochemical gradient in the chloroplast is a gradient of electrochemical potential of ions which move across the membrane of the chloroplast during the photosynthesis process. The proton gradient across the thylakoid membrane drives the ATP synthesis during photosynthesis.
