It is anerobic respiration. Lactic acid fermentation is taken place
In the absence of oxygen after glycolysis, muscle cells will produce lactic acid through the process of fermentation. This allows the cells to regenerate NAD+ needed for glycolysis to continue in the absence of oxygen.
Glycolysis
anaerobic respiration, which does not require oxygen. This process produces lactic acid as a byproduct, which can lead to muscle fatigue and soreness.
Myoglobin
The muscle continues to contract in the absence of oxygen through Glycolysis. Glycolysis is the breakdown of glucose to pyruvic acid in the cytoplasm of a cell. It is called an anaerobic process, because it does not require oxygen.
Lactic Acid Fermentation
The process primarily responsible for the development of the present percentage of free oxygen in the Earth's atmosphere is photosynthesis. This process is carried out by plants, algae, and cyanobacteria, which convert carbon dioxide and water into oxygen and glucose with the help of sunlight. Over time, this has led to the accumulation of oxygen in the atmosphere to its present level of around 21%.
Anaerobic respiration is an energy-releasing process that does not require oxygen. This process occurs in the absence of oxygen and can be found in certain microorganisms, as well as in muscle cells during intense exercise.
If oxygen is not present in the cell, the process of cellular respiration cannot proceed normally. In the absence of oxygen, anaerobic respiration occurs. This process involves glycolysis followed by either lactic acid fermentation in animal cells or alcoholic fermentation in yeast and some bacteria to produce ATP.
When oxygen is no longer present in the cells, anaerobic respiration takes place. This process involves the breakdown of glucose to produce energy without the use of oxygen. One of the byproducts of anaerobic respiration in humans is lactic acid.
When the body produces lactic acid because it doesn't have enough oxygen this makes a muscle sore.
