The nucleoid is a region of cytoplasm where the chromosomal DNA is located. It is not a membrane bound nucleus, but simply an area of the cytoplasm where the strands of DNA are found.Most bacteria have a single, circular chromosome that is responsible for replication, although a few species do have two or more.he function of a nucleoid is it contains genetic material and the DNA determines what proteins and enzymes an organism can synthesise.
There are two distinct phases in the pathway. The first is the oxidative phase, in which NADPH is generated, and the second is the non-oxidative synthesis of 6-carbon sugars. For most organisms, the pentose phosphate pathway takes place in the cytosol; in plants, most steps take place in plastids.Similar to glycolysis, the pentose phosphate pathway appears to have a very ancient evolutionary origin.or most organisms, the pentose phosphate pathway takes place in the cytosol; in plants, most steps take place in plastids.

Fructose bisphosphatase (EC 3.1.3.11) is an enzyme that converts fructose-1,6-bisphosphate to fructose 6-phosphate in gluconeogenesis and the Calvin cycle which are both anabolic pathways.Fructose bisphosphatase catalyses the reverse of the reaction which is catalysed by phosphofructokinase in glycolysis.one of these groups have been found in archaea so far, though a new group of FBPases (FBPase IV) which also show inositol monophosphatase activity has recently been identified in archaea. A new group of FBPases (FBPase V) is found in thermophilic archaea and the hyperthermophilic bacterium Aquifex aeolicus.
