The non-cyclic electron flow (Z-scheme) produces

ANADPH, ATP and O2 from water
BOnly ATP without NADPH or O2
COnly O2 without ATP or NADPH
DGlucose directly from CO2 and water
Answer & Solution
Correct answer: A. NADPH, ATP and O2 from water
**Non-cyclic flow:** water -> PS II -> ETS -> PS I -> NADP+. Outputs are O2 (from water splitting), ATP (chemiosmosis along the chain), and NADPH (final reduction). Cyclic flow (PS I only) yields ATP only.
