Adenosine 5'-triphosphate, or ATP, is the most abundant energy ... When energy is abundant, eukaryotic cells make larger, energy-rich molecules to store their excess energy. The resulting sugars ...

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 ...

Through a series if small steps, free energy is released from sugar and stored in carrier molecules in the cell (ATP and NADH, not shown). On the right, the direct burning of sugar requires a ...

Some of this energy is used to split water into hydrogen and oxygen. Hydrogen and ATP are both transferred to the second stage of photosynthesis. Some of the oxygen produced can be used by the ...
