Glycolysis itself anaerobic process and forms pyruvate. If there is oxygen present, pyruvate is reduced to acetyl-coenzyme A; if there is no oxygen present, pyruvate goes through fermentation, forming either lactic acid or ethanol.
anaerobic glycolysis is more speedy then aerobic glycolysis
Glycolysis is only anaerobic but it can proceed in both aerobic and anaerobic conditions. Any how glycolysis is speedy as compared to aerobic respiration
Cellular RespirationSource: Holt Biology by Johnson Raven* Aerobic cellular respiration. Anaerobic cellular respiration yields a net gain of 2 ATP molecules for each glucose molecule broken down. Aerobic respiration yields a variable number, but always more than ten times as many ATP molecules.
Fermentation
Glycolysis is the first step of cellular respiration. Glycolysis produces much less ATP (2) than the combined total ATP of the rest of aerobic respiration (about another 30). The majority of ATP is produced by the electron transport chain. Cellular respiration is considered more efficient than glycolysis because it produces significantly more ATP. ATP stands for adenosine triphosphate.
2. ATP production in glycolysis is 2 and the biocide is blocking ATP production in everything but glycolysis.
More ATP is produced than is used.
mass
Glycolysis: 2 ATP per molecule of glucose Total ATP yield of aerobic respiration (including glycolysis): 36 ATP per molecule of glucose (theoretical, less in reality due to leaking of protons across the mitochondrial inner membrane)
Anaerobic respiration only glycolysis occurs which forms 2ATP. However, in aerobic respiration there is the Krebs cycle which is responsible for making 2 ATP and the electron transport chain which is responsible for making 30 ATP. Most textbooks say that for aerobic respiration around 36-38 ATP is made. When compared to the 2 from anaerobic it is a major difference in energy production.
The aerobic system, also known as aerobic glycolysis, powers continuous steady state exercise longer than three to four minutes. In the aerobic system energy (ATP) is produced through Pyruvic Acid and Lipid/Protein fragments entering the Kreb Cycle and the Electron Transport Cycle (McArdle, 1991).

There are anaerobic and aerobic types of cellular respiration. Anaerobic (including glycolysis) respiration does not involve oxygen. Aerobic (including the Kreb's, or citric acid, cycle and oxidative phosphorylation) respiration requires oxygen, and generates much more energy than anaerobic respiration.
Aerobic respiration produces 36 ATP from one glucose molecules. Anaerobic respiration produces only 2. Two glucose molecules are produced during glycolysis. In addition to producing ATP from ADP, glycolysis also converts NAD+ to NADH. If no oxygen is available, more energy needs to be produced from glycolysis. However, for glycolysis to occur, NAD+ must be regenerated from NADH. Thus, in a process known as anaerobic fermentation, NAD+ is regenerated from NADH. Fermentation doe snot fully oxydize glucose. After glycolysis, the glucose molecule has been converted into two molecules of pyruvate. Fermentation uses pyruvate to convert NAD+ back to NADH so it can be used for another round of glycolysis. If oxygen is present, the two pyruvate molecules from glycolysis can be fully oxydized in a process known as aerobic respiration. This process consists of the citric acid cycle and the electron transport chain. The process is beyond the scope of this post, but aerobic respiration basically produces more NADH and FADH2 from pyruvate and uses the NADH/FADH2 molecules to oxydize O2 to H2O. The Krebs cycle produces 2 ATP and the electron transport chain produces 32 ATP. Thus, aerobic respiration is a far more efficient means of energy production.

Fermentation
Aerobic respiration requires oxygen, whereas anaerobic respiration occurs in the absence of oxygen. Aerobic respiration is completed in three steps viz, Glycolysis, Kreb's Cycle and Electron transport chain; whereas anaerobic respiration is completed in Glycolysis. Aerobic respiration involves carbon dioxide as the major excretory by-product, whereas in anaerobic respiration, along with carbon dioxide, ethyl alcohol (in case of plants) and lactic acid (in case of animals) is liberated.
