Glucose is a simple sugar. It is what your body uses for fuel. Your intestines break down the food you eat into protein and glucose. In the process of glycolysis, cells use glucose to generate energy. This process partially breaks down glucose, ultimately resulting in pyruvate in aerobic settings (when oxygen is present) and lactate in anaerobic settings (when oxygen is not present). Glycolysis and phosphagen work together to produce energy in anaerobic settings. This energy is used to help overcome external forces such as gravity, weight, and friction
Glycolysis is the first stage of cellular respiration and it typically takes place in the cytoplasm of both eukaryotic and prokaryotic living cells.
Also, glycolysis is an anaerobic reaction because it doesn’t require the use of oxygen.
Typically, a glucose molecule acts as the primary source of energy for living organisms such as autotrophs (plants).
Phosphagen is also referred to as a macroergic compound and it is an organic phosphate compound found in the muscular tissues of animals, which serves as the quickest and most powerful source of energy when moving muscles.
Basically, phosphagen is a high-energy storage compound because it transfers high-energy phosphate to adenosine diphosphate (ADP) to form adenosine triphosphate (ATP).
Aerobic glycolysis (occurring in the presence of oxygen) is characterized by a slow rate of adenosine triphosphate (ATP) production and as such, it is mainly used during physical exercises having longer duration or for lower-intensity activities after exhausting the phosphagen and anaerobic systems (absence of oxygen).
During anaerobic glycolysis (lactic acid system), both glycolysis and phosphagen produces energy in the form of adenosine triphosphate (ATP), which is used quickly for intense effort.
