... Pheo and from P700 to AO, and this is where "light" energy is consumed. 6. Proton Gradient and ATP Synthesis The light reactions provide not only the reducing power in NADPH ... a proton motive force (pmf) across the thylakoid membrane. This pmf is composed of two components:an electrical potential across the thylakoid membrane and a proton gradient across the thylakoid membrane. The proton gradient ...

... guess what happens here, but a good guess would be that a proton (H+) pump moves H+ ions out of the midrib cells and ... that this calcium might move into the cells by following the charge gradient. After all, if H+ ions left, the cell now has negative charges ... fibers. Once the calcium enters the cell, it creates an osmotic gradient. There is now a greater proportion of Ca++ and smaller proportion of ...
