The body's metabolic process usually involves the oxidation of glucose. When the body cannot get enough oxygen to meet the demands for energy, cells begin using the anaerobic process (without oxygen).
This process breaks down glucose and glycogen to lactic acid which then diffuses into the blood stream.
The result of anaerobic metabolism can be seen in athletes who are rapidly using energy, at a faster rate than oxygen can be re-supplied to the muscles. Lactic acid build up impedes muscle functions, causing pain and sometimes nausea.
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.
Yes, neurons have the ability to perform anaerobic metabolism, particularly during periods of high energy demand or when oxygen supply is limited. However, neurons primarily rely on aerobic metabolism for their energy needs due to their high metabolic activity and constant energy requirements.
Red blood cells rely on anaerobic metabolism for ATP production because they lack mitochondria and thus cannot perform aerobic respiration.
The end product of the anaerobic phase of glucose metabolism is lactate (lactic acid). This process occurs in the absence of oxygen when energy needs are high.
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.
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.

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 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.
