How are glycolysis and phosphagen systems used in both aerobic and anaerobic exercise?

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

it's false.
