Monosaccharides are joined by which type of reaction to form larger carbohydrates?

Explanation:
Joining monosaccharides into larger carbohydrates happens through condensation (dehydration synthesis). When two sugar molecules meet, a hydroxyl group from one and a hydrogen from the other are removed, forming water and creating a covalent glycosidic bond between them. This is the process that builds disaccharides like sucrose and maltose and extends into polysaccharides such as starch and glycogen. Hydrolysis is the opposite reaction: it breaks these glycosidic bonds by adding water. Oxidation and reduction are redox changes that alter electron distribution, not the actual linkage between sugar units.
