lactic acid
In plant and animal cells, it is a process in which energy is released from food molecules such as glucose without requiring oxygen. Some aerobic plants and animals are able to use anaerobic respiration for short periods of time. For example, during a sprint, human muscles can respire anaerobically.Unfortunately, lactic acid is produced and accumulates until the muscles cannot continue working. Anaerobic respiration in humans is less efficient than aerobic respiration at releasing energy, but releases energy faster. This explains why humans can run faster in a sprint than over longer distances. When humans stop after a sprint, they have to continue breathing more heavily for a while. This is to take in extra oxygen in order to break down the accumulated lactic acid on top of the normal breakdown of sugar in aerobic respiration. The body is paying back the oxygen debt built up during the sprint. . Anaerobic respiration is the process by which non-oxygen dependent organisms breath. It is mostly commonly used in the process of fermentation. Anaerobic respiration is respiration that uses electron acceptors other than oxygen. Anaerobic respiration can be found in protozoans and bacteria.Anaerobic respiration is a type of cellular respiration. It occurs when oxygen is not available or is available in very low quantities.It is also a respiration in the absence of oxygen. Oxygen is not used as the final electron acceptor.
They didn't have weightlifting back then. Instead they built their muscles by preforming outdoor activities. People during that time period were always physically active. They had chores to do so they built their muscles through their chores.
They also cause the muscles of the uterus to contract, thus helping the uterus shed the lining built up during the first part of a woman's cycle.
True.
Glucose It is the primary substrate.Glucose is oxizdied into CO2
Before a massage, muscles may be tense, tight, and knotted due to stress or physical activity. During a massage, the muscles relax and blood flow increases, helping to release tension and improve flexibility. After a massage, muscles may feel looser, more relaxed, and less sore due to the release of built-up tension and improved circulation.
When we exercise CO2 is built up in body at a faster rate than at rest. During exercise our body needs more energy. Our body produces energy through cellular respiration. During cellular respiration we convert sugar and oxygen into CO2 and water. Thus the more we exercise the more cellular respiration and thus more CO2 and thus we breath harder and pump blood faster to meet demands we place on body. After exercise we no longer have as much CO2 built up therefore our bodies can return to slower breathing and heart rate.
Hollow, light bones. Big chest muscles.
your body has 650 muscles to be correct and its more complicated yet more efficient than any machine ever built
It was built in 1961 during the Cold War.
Depends on how you mean, sprinting is a form of anaerobic respiration (where no oxygen is actually needed), however lactate builds up as a result meaning you will have to stop after a short period of time. However you will still be breathing to repay the oxygen debt that's built up, to counteract the buildup of lactate (which is toxic to the body in most cirumstances).
Horses are built to run, with powerful muscles in the fore- and hind-quarters, long spindly legs, large lungs and a stout heart.
