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.
9 pentose phosphate pathway (7). 1  1. Pentose Phosphate PathwayThree main functions:1) Supply the cell with NADPH in order to: a) provide reducing power for biosynthetic reactions.2  b) serve as a biochemical reductant (e.g., maintain glutathione levels).3  c) be utilized by the cytochrome P450 monooxygenase system. 1.

The cycle consumes acetate (in the form of acetyl-CoA) and water, reduces NAD+ to NADH, and produces carbon dioxide as a waste byproduct. The NADH generated by the citric acid cycle is fed into the oxidative phosphorylation (electron transport) pathway. The net result of these two closely linked pathways is the oxidation of nutrients to produce usable chemical energy in the form of ATP. In eukaryotic cells, the citric acid cycle occurs in the matrix of the mitochondrion.
