The electron transport chain during the light reaction of photosynthesis proceeds as follows:
1. Pheophytin acts as the primary electron acceptor in Photosystem II.
2. Electrons are transferred to Plastoquinone, which carries them to the Cytb6-f complex.
3. The Cytb6-f complex facilitates the transfer of electrons to Plastocyanin, which carries electrons to Photosystem I.
Correctly match the enzymes used as selectable markers (Group I) and the chemicals used for their selection (Group II):
Correctly match the economically important specialized metabolites (Group I) with their broad chemical classes (Group II):
