Humans (actually many organisms but here I will refer to humans) produce energy by two metabolism cycles - Glycolysis and Krebs cycle.
In Glycolysis, DHAP (DiHydroAcetone Phosphate) produces glycerol-1-phosphate as an intermediate.
In Krebs Cycle or Citric Acid cycle, different molecules with the help of enzymes undergo reactions to produce ATP.
Glycerol-1-phosphate further undergoes or utilized in Glycolysis to produce final product Pyruvate, ATP, NADH. Thus though human can produce energy from Glycerol-1-phosphate, it is not a direct energy giving molecule.
ATP (Adenosine TriPhosphate) has high-energy phosphate bond. When ATP is hydrolysed to ADP, it release 30.5 Kj/mol energy and when ADP is hydrolysed to AMP, it again releases 30.5 Kj/mol energy. Direct hydrolysis of ATP produces energy which is the key difference with glycerol-1-phosphate.
