Analysis of Molecules for Long-term Energy Storage

1. Glycogen:

   • Glycogen is a polysaccharide that serves as a form of energy storage in animals and fungi. It is primarily stored in the liver and muscle tissues and can be rapidly converted to glucose when energy is needed, making it a significant long-term energy storage molecule.

2. ATP (Adenosine Triphosphate):

   • ATP is not used for long-term energy storage. Instead, it is a short-term energy carrier that provides immediate energy when needed. It is continuously produced and consumed in metabolic processes, thus not suitable for long-term storage.

3. Proteins:

   • While proteins can serve as an energy source, they are primarily used for building and repairing tissues. The body prefers to use carbohydrates and fats for energy storage, so proteins are not a primary molecule for long-term energy storage.

4. Fats:

   • Fats, or triglycerides, are one of the main forms of long-term energy storage in cells. They are stored in adipose tissue and provide a concentrated source of energy, yielding more than double the energy per gram compared to carbohydrates.

5. Starch:

   • Starch is a polysaccharide that serves as a long-term energy storage molecule in plants. It can be broken down into glucose when energy is required, making it an important energy reserve for plant cells.

Final Answer

The types of molecules that cells use for long-term energy storage are:

1. Glycogen
2. Fats
3. Starch

ATP and proteins do not primarily serve as molecules for long-term energy storage.
