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 function of the electron transport chain is to produce a transmembrane proton electrochemical gradient as a result of the redox reactions. If protons flow back through the membrane, they enable mechanical work, such as rotating bacterial flagella.n the mitochondrial electron transport chain electrons move from an electron donor (NADH or QH 2) to a terminal electron acceptor (O 2) via a series of redox reactions.
