Question restatement: Which of the following is made from one glucose molecule and one fructose molecule linked together?

Option 1: Sucrose. This is the disaccharide formed specifically by a glucose molecule linked to a fructose molecule via a glycosidic bond, producing table sugar commonly found in plants. The composition matches the prompt exactly, so this pairing is correct.

Option 2: Lactose. Lactose is a disaccharide composed of glucose and galactose, not glucose and fructose. The second sugar is galactose, which distinguishes lactose from the glucose–fructose combination in question.

Option 3: Maltose. Maltose consists of two glucose units joined together. It does not include fructose at all, so it does not fit the described one glucose plus one fructose structure.

Option 4: Amylose. Amylose is a polysaccharide, a polymer made up of many glucose units linked in long chains. It is not a disaccharide, and it contains only glucose, not a mix of glucose and fructose.

Option 5: Protein. Proteins are polypeptide chains composed of amino acids, not sugar molecules. Given the chemical nature of sugars versus proteins, this option is categorically incorrect for the described linkage.
