Which of the Following Has the Most Stored Energy

Question

Which of the following has the most stored energy?  
A) Phosphoglycerate (PGA)
B) Ribulose bisphosphate (RuBP)
C) Phosphoglyceraldehyde (PGAL)
D) Glucose
E) Rubisco

Accepted Answer

Glucose has the most stored energy among the given options, as it is a carbohydrate and is the end product of photosynthesis, containing six carbon atoms with a high potential energy in its bonds. The other options, such as PGA, RuBP, PGAL, and Rubisco, are intermediate compounds involved in the process of photosynthesis and do not have as much stored energy as glucose.
