11 of 14
Explain why the principle of macromolecules being able to be deconstructed into building blocks, which can then be reconstructed into different macromolecules is the basis for life as we know it
Macromolecules can be broken broken down into smaller, useful molecules, which can be built into lots of other very useful compounds for life - they also release lots of energy, which is needed for life
