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 electron transport chain in the cell is the site of oxidative phosphorylation in prokaryotes. The NADH and succinate generated in the citric acid cycle are oxidized, releasing energy to power the ATP synthase. Oxidative phosphorylation (or OXPHOS in short) is the metabolic pathway in which cells use enzymes to oxidize nutrients, thereby releasing energy which is used to reform ATP. In most eukaryotes, this takes place inside mitochondria. Almost all aerobic organisms carry out oxidative phosphorylation.
