Anaerobic metabolism converts glucose into energy without the use of oxygen. This process results in the production of lactate or lactic acid as a byproduct.
Monera bacteria can be aerobic (requiring oxygen for metabolism) or anaerobic (able to thrive without oxygen). Some species are capable of both aerobic and anaerobic metabolism, depending on the environment they are in.
Facultative anaerobic bacteria can switch between using aerobic and anaerobic metabolism depending on oxygen availability. Obligate anaerobic bacteria cannot survive in the presence of oxygen and rely only on anaerobic metabolism, while obligate aerobic bacteria require oxygen for survival and use aerobic metabolism exclusively.
Lactic acid.
Lactic acid accumulates in cells as a result of anaerobic metabolism. This occurs when cells do not have enough oxygen to produce energy through aerobic respiration, and instead rely on anaerobic glycolysis to generate ATP.
Aerobic respiration requires oxygen and occurs in the presence of oxygen, producing more ATP compared to anaerobic respiration. Anaerobic respiration occurs in the absence of oxygen and generates less ATP.

lactic acid
Cycling is both an anaerobic and aerobic activity. It primarily relies on aerobic metabolism for sustained energy, but also involves anaerobic metabolism during intense bursts of effort, such as sprinting or climbing hills.
Lactic acid.
The direct result of anaerobic metabolism during hypoxic cell injury is the production of lactic acid. In the absence of oxygen, cells are forced to rely on anaerobic metabolism, leading to the accumulation of lactic acid and a decrease in pH, which can further damage the cell.
Aerobic metabolism produces more ATP (energy) per molecule of glucose compared to anaerobic metabolism, making it more efficient for supplying energy to cells. Aerobic metabolism also generates less lactic acid, reducing the risk of muscle fatigue and allowing for longer sustained activity. Additionally, aerobic metabolism allows for the utilization of a wider range of substrates for energy production compared to anaerobic metabolism.

Anaerobic organisms do not use oxygen in their metabolism. These organisms can generate energy through fermentation or anaerobic respiration, which does not require oxygen. Examples include certain types of bacteria and yeast.
