CAIE A-Level Biology A2 13.1.8 Cyclic Photophosphorylation Questions question 1
Photosynthesis is the energy transfer process that occurs in chloroplasts.
Fig. 5.1 shows some biochemical events that occur in a chloroplast during the light-dependent stage of photosynthesis. Photosystems I and II (PSI and PSII) and some associated proteins of the thylakoid membrane are shown.
Fig. 5.1
The group of proteins labelled C, PSI and the protein labelled E are involved in a specific biochemical process during the light-dependent stage of photosynthesis.
Name this specific biochemical process and the protein labelled E.
