Aerobic respiration is a type of cellular respiration that requires oxygen atoms as final electron acceptors. Anaerobic respiration is a type of cellular respiration that does not require oxygen atoms as final electron acceptors. Fermentation is the partial oxidation of sugar to release energy using an endogenous organic molecule rather than an electron transport chain as the final electron acceptor. In aerobic respiration, hydrogen ions, generate H2O. Anaerobic respiration uses inorganic chemicals other than oxygen as the final electron acceptor. The anaerobic bacterium reduces sulfate to hydrogen sulfide gas whereas anaerobes utilize nitrate to produce nitrite ions, nitrogen oxide, or nitrogen gas. Products of anaerobic respiration such as nitrate help identify species of microbes. Fermentation pathways are metabolic reactions that oxidize NADH and NAD+ while reducing cellular organic molecules. Fermentation has no need for electron acceptors. Two common pathways for fermentation that reduce pyruvic acid to lactic acid or ethanol, oxidize NADH. Fermentation products are waste to cells that make them useful to humans which include ethanol, drinking alcohol, lactic acid, production of cheese. There are dangerous fermentation products as well. One of them is fermentation products of the bacterium Clostridium perfringens, the necrosis of muscle tissue with gangrene. Fermentation reactions can be used to identify microbes like proteas ferments glucose. Anaerobic respiration and aerobic respiration are different because one requires oxygen for electron transport while the other one does not. They are the same because they both transport electrons. Aerobic respiration requires oxygen, is a substrate-level and oxidative phosphorylation, the final electron acceptor is oxygen and the potential molecules of ATP produced per molecule of glucose is 38 in prokaryotes and 36 in eukaryotes. Anaerobic respiration does not require oxygen, is substrate-level and oxidative phosphorylation, the final electron is NO2 negative, SO42 negative, CO32 negative or externally acquired organic molecules and the potential molecules of ATP produced per molecule of glucose is 2-36.

Hello class and Dr. Morata,
Both aerobic and anaerobic are respiration, one occurs in the presence of oxygen, while the other occurs in the lack of oxygen (Bauman, 2017, p.142). Aerobic respiration is an aerobic process. It is completed in the presence of oxygen (Bauman, 2017, p.142). The use of oxygen allows glucose to be completely broken down (Bauman, 2017, p.142). Carbon dioxide, water, and a substantial amount of energy are the final products (Bauman, 2017, p.142). It can be found in all living things. Fermentation is a type of anaerobic process. The glucose is broken down anaerobically into carbon dioxide, alcohol, and a small quantity of energy (Bauman, 2017, p.142). It can be discovered in microorganisms.
Substrate-level phosphorylation generates some ATP in respiration in both glycolysis and the Krebs cycle, but that oxidative phosphorylation via chemiosmosis using the reducing power of NADH and FADH2 generates the majority of ATP (Bauman, 2017, p.141). We also discovered that some microbes employ fermentation to produce NAD+ as an alternative source (Bauman, 2017, p.141).
