1a.Which is not a member of the central pathways

   the pentose phosphate pathway
   glycolysis
   the calvin cycle
   the tricarboxylic acid cycle

1b.Prokaryotes can obtain nitrogen for biosynthesis directly from
   ammonia (NH4+) in soil or water
   nitrous oxide (N2O) in the atmosphere
   dinitrogen (N2) in the atmosphere
   a AND c

Solution

1.Calvin cycle

Central metabolic pathways ars those that provide precursor metabolites to otherg pathways. The major pathways are glycolysis, the pentose phosphate pathway(PPP) and krebs cycle.

2.ammonia (NH4+) in soil or water.

Biological nitrogen fixation (BNF) occurs when atmospheric nitrogen is converted to ammonia by an enzyme called a nitrogenase.
