The processes that use the mechanisms are: Cellular respiration â ATP is generated by oxidation of organic molecules, the passage of electrons down an electron transport chain, and chemiosmosis. The final electron acceptor is almost always inorganic. Aerobic â the final electron acceptor is O 2.
The Sumerians lived in Mesopotamia around 4000 BC. Mesopotamia or the Fertile Crescent was a region in the Middle East between the Tigris and Euphrates rivers, in the territory of modern Iraq, Iran and Syria.
The first Empire to rule all of Mesopotamia was the Akkadian Empire. It lasted for around 200 years from 2300 BC to 2100 BC. The Akkadians lived in northern Mesopotamia while the Sumerians lived in the south. They had a similar government and culture as the Sumerians, but spoke a different language.
