Plants contain two types of GOGAT; one accepts electrons from NADH, and the other accepts electrons from ferredoxin (Fd); which one of the following statements is correct?

#Unit 6. System Physiology – Plant
  1. The NADH type of the enzyme (NADH-GOGAT) is located in plastids of nonphotosynthetic tissues such as roots or the vascular bundles of developing leaves
  2. In vascular bundles of developing leaves, NADH-GOGAT is involved in the assimilation of NH4 + absorbed from the rhizosphere
  3. In roots, NADH-GOGAT assimilates glutamine translocated from roots or senescing leave
  4. The ferredoxin-dependent type of glutamate synthase (Fd-GOGAT) is found in cytoplasm and serves in photorespiratory nitrogen metabolism
