Proteins (amino acids) are also used as body fuels.
Some amino acids can be converted into glucose (gluconeogenesis)
Some can be converted into various intermediates of oxidative metabolism

Formation of ATP by PC breakdown.
The simplest of the energy system.
Phosphocreatine (PC) is a high-energy phosphate molecule that store in
the muscle cells.
Basic Energy Systems
All plants & animals depend on energy to sustain life.
Humans derive this energy from food.
Many forms: chemical, electrical, electromagnetic, thermal, mechanical &
All energy forms are interchang
