For instance, since your cells can either burn nutrients immediately or store them for later use, the cells use ATP to help them determine which they should do. If a cell has plenty of ATP, the ATP signals the cell to store nutrients rather than burning them. If a cell is low on ATP, however, that signal indicates that the cell should burn ...
Why is ATP important?
Image Credit: aerogondo/iStock/Getty Images.

How much ATP can a human body make?
Even though human cells can make about 30 ATP per glucose molecule -- and can also make large and varying amounts of ATP from burning protein and fat -- not all glucose metabolism results in the production of that much ATP. You can only make two ATP molecules per glucose if you're burning sugar without oxygen, a process called anaerobic metabolism.
How many molecules of ATP are produced by the cells that break down glucose?
They use the energy liberated from breaking down a single molecule of glucose to make approximately 30 molecules of ATP.
What is the chemistry of ATP?
ATP Chemistry. ATP is a relatively small molecule that serves as an "energy intermediate" in human metabolism. In essence, your cells extract the chemical energy from various nutrient molecules like proteins, carbohydrates and proteins, and use the chemical energy to make ATP.
