    Does chemiosmosis still occur here, or is that only in non-cyclic photophosphorylation?

    Yes! Chemiosmosis still happens as it is part of the process of forming ATP.

    When the proton pump actively transports protons from the stroma into the thylakoid space and the protons accumlate there, you set up the electrochemical gradient. As there is a high conc. of protons in that space, they diffuse through the stalked particle. As they diffuse across, they provide the energy so ADP can combine with P to for ATP. This is chemiosmosis.

    So whether cyclic or non-cyclic, ATP is formed in both.

    Thank you! I just realised that it's called cyclic photoPHOSPHORYLATION (duh at myself!) so the H+ gradient must be there to generate ATP😂

    No problem. Do you do WJEC? If so, I do WJEC too.
