IB Biology Topic C1.2.1: ATP as the Molecule That Distributes Energy Within Cells Notes

ATP is built from three parts, with high-energy bonds between its phosphates

ATP is a nucleotide made of three parts.

Adenine: a nitrogen-containing base.
Ribose: a five-carbon sugar.
Three phosphate groups: linked in a chain, with the terminal bond holding high-energy potential.

Note

The three phosphate groups are negatively charged, so they repel each other.
This makes the bonds unstable and high-energy, ideal for quick energy release.
