Choose the incorrect statements about photosynthesis dark reaction ?

#Section 2: General Biology
  1. The light dependent enzymes which are activated by Ferredoxin–thioredoxin system, contain oxidised di-sulfide bonds (—S—S—) in its active form
  2. C3 cycle or Calvin–Benson cycle is regulated by Photosystem I
  3. The activation of enzymes of the Calvin– Benson cycle starts in the light with the reduction of ferredoxin by the photosynthetic electron transport chain (Chl)
  4. The series of Ferredoxin–thioredoxin system in presence of light is,  2 Ferredoxin (oxidized) to 2 Ferredoxin (reduced)→ Trx(s−s) to Trx(SH) → Ferredoxin– thioredoxin reductase (s−s) to Ferredoxin– thioredoxin reductase(SH)→ Enzyme (inactive)(s−s) to Enzyme (active)(SH)
