Under conditions of very high light intensity, excess absorbed solar energy is dissipated by the action of photoprotective proteins in the thylakoid membrane. Explain why it is advantageous for these proteins to be activated by buildup of the proton gradient across the membrane.
Assume a pH gradient of 4.0 units across a thylakoid membrane, with the lumen more acidic than the stroma.What is the standard free energy change per mol O2 produced? How does this compare to the energy required to drive the synthesis of ATP?
Draw a basic drawing of a thylakoid membrane that is actively engaged in chemiosmosis and mark the two compartments it divides. Add the ATP synthase complex, indicate the proton gradient, and define which compartment ATP is generated in.
