Glucose Storage in Plants and Animals

Glucose storage in plants and animals helps cells manage energy for metabolism. Sugar is a simple carbohydrate, and cells use it because a lot of energy is stored in its bonds. Consumed carbohydrates often come from photosynthesizing organisms, especially plants.

Plants make glucose during photos...

Simple sugars, such as glucose, are a primary source of energy in most living organisms. When food is abundant, organisms convert these simple sugars into specialized energy storage molecules, such as starch and glycogen.

When the food supply gets limited, the energy stored in the covalent bonds of these complex storage molecules can be u...
