To begin, we need to identify what maltose is made of and what the image shows. Maltose is a disaccharide composed of two glucose units joined by an α(1→4) glycosidic bond.
Option 1: 'glucose and lactose' would imply one glucose unit paired with a lactose molecule, which is incorrect because lactose is a disaccharide (galactose + glucose) itself, not a single monosaccharide unit. The image shows just two monosaccharide rings linked together, not a glucose-lactose combination.
Option 2: 'lactose and galactose' is also incorrect. Lactose is galactose linked to glucose, not two single monosaccharide units of glucose. The phrase suggests a disaccharide plus a monosaccharide, which doesn’t fit the structure in the image.
Option 3: 'fructose and glucose' would describe the disaccharide sucrose (glucose–fructose) or another linkage, but maltose specifically contains two glucose units, not glucose and fructose. The depicted rings are both identical, indicating two glucose rings.
Option 4: 'glucose and glucose' correctly reflects maltose as a dimer of glucose molecules connected by a glycosidic bond. The two sugar rings in the image are of the same type, consistent with two glucose units.
In summary, the remaining options either pair glucose with a different monosaccharide, or describe a compound that is not maltose. The only choice that matches two identical monosaccharide units (both glucose) is the glucose–glucose option.
