Anabolic reactions build new molecules and/or store energy. The energy of catabolic reactions is used to drive anabolic reactions. The energy for chemical reactions is stored in ATP. Often when I ask students What is ATP the answer they give is Energy.
First, we need to know what ATP really is - chemically, it is known as adenosine triphosphate. ATP is a usable form of energy for cells - the energy is trapped in a chemical bond that can be released and used to drive other reactions that require energy (endergonic reactions). Photosynthetic organisms use energy from sunlight to synthesize their own fuels.
