True.
Work Step by Step
A macromolecule does contain hydrogen bonds that are typically weak on their own, but when they are in a macromolecule, they are noticeably stronger and less likely to fall apart by thermal motion. This is because there are simply a lot of them, and when there is a lot versus a little, they are stronger. It also helps that as the bonds are very specifically placed, having them in excess makes them stronger than alone.
