ATP works by losing the endmost phosphate group when instructed to do so by an enzyme. This reaction releases a lot of energy, which the organism can then use to build proteins, contact muscles, etc.

ATP (adenosine triphosphate) is the energy-carrying molecule used in cells because it can release energy very quickly. Energy is released from ATP when the end phosphate is removed. Once ATP has ...

This process, called photosynthesis, is essential to the global carbon cycle and organisms ... and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced ...

In general, the energy to synthesize ATP molecules must be obtained from ... these mechanisms ultimately converge onto a common pathway, the TCA cycle, occurring within the mitochondria (Figure ...
