Answer:
Glucose
Step-by-step explanation:
Glucose is a source of energy and it is stored in the body (in the form of glycogen) and it can also dissolve in water.
Glucose produces energy (in the form of ATP) after its complete breakdown via various pathways starting with glycolysis through the tricarboxylic acid cycle (TCA) and eventually the electron transport chain (ETC) with the eventual net production of 34 ATPs.
One of the physical properties of glucose is that it readily dissolves in water.
