Answer: Non-cyclic electron transport in light reactions.
- A The sequential transfer of electrons along the mitochondrial respiratory chain
- B Cyclic electron flow restricted entirely to Photosystem I alone
- C Non-cyclic electron transport in light reactions
- D The semi-conservative copying of the genome prior to cell division
Correct answer: C. Non-cyclic electron transport in light reactions
Explanation: Z-scheme: electrons from water (via PS II) and from PS I flow in a Z-shaped path, generating ATP and NADPH in non-cyclic photophosphorylation.
