Answer:
The correct answer is- C6H12O6
Step-by-step explanation:
Glucose is a source of energy which is produced by green plants with the help of carbon dioxide and water in the presence of sunlight. This is a form of stored energy which is then released when oxidation of glucose takes place.
Some of the energy released during the oxidation of glucose is used to produce ATP from ADP which is another form of energy which cell requires to perform metabolic activities.
Some of the energy during glucose oxidation is released in the environment and heat. Therefore glucose(C6H12O6) is the molecule best described as an energy-rich molecule.
