Carbon bonds primarily store energy, which is crucial for biological processes. Glucose serves as a key energy source due to its stored energy in carbon bonds, and ATP is produced from this energy. Water is involved in many processes, but it does not store energy in carbon bonds. ;
The correct answer to the question is B: energy. Carbon bonds primarily store energy, which is released during processes such as cellular respiration and is vital for the production of ATP. Glucose, another option, is a source of energy rather than the storage medium itself.
