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.

Oxidative phosphorylation (or OXPHOS in short) is the metabolic pathway in which the mitochondria in cells use their structure, enzymes, and energy released by the oxidation of nutrients to reform ATP.uring oxidative phosphorylation, electrons are transferred from electron donors to electron acceptors such as oxygen, in redox reactions. These redox reactions release energy, which is used to form ATP.
