-What is the role of ATP in the cell?

The nucleotide coenzyme ATP is the most important form of chemical energy in all cells. Cells make use of ATP for:

Chemical work - ATP supplies energy to synthesize macro-molecules, and therefore the organism.

Transport work - ATP supplies energy needed to pump substances across the plasma membrane.

Mechanical work - ATP supplies energy for cellular movements.

-How do cells store for the long term? How is it then broken down to fuel the cells?

When cells need to store chemical energy in a more stable form for long-term storage, the energy from ATP to build more stable molecules. ATP is then further broken down into ADP and energy. The fuel for cellular respiration is glucose, which is formed when carbohydrates, such as starch and sucrose are broken down. If too few carbohydrates are available to meet an organism's energy needs, other molecules, such as fats, can be broken down to make ATP.
