The monosaccharide glucose is stored as glycogen in humans and other vertebrates. Glycogen is a polymer of glucose, and it is usually stored in liver and muscle cells as an energy source. Whenever a human body needs energy, glycogen is broken down via hydrolysis to release glucose that cells can absorb through their cell membranes.

Which argument is supported by these facts occurring in humans and other vertebrates?


A)Glucose’s small size allows it to be transported through cell membranes, which demonstrates that its size is related to its function.


B) Glucose is soluble in water which allows it to be transported through cell membranes, which demonstrate that its solubility is related to its function.


C) Glucose is an energy source because of its large proportion of carbon atoms, which demonstrates that its composition is related to its function.


D) Glucose is quickly broken down by liver and muscle cells to provide energy, which demonstrates that its type of chemical bonds is related to its function.
