Final Answer:
a. The chemical reaction that formed the disaccharide sucrose from the glucose and fructose monomers is a condensation reaction.
b. A condensation reaction formed sucrose from glucose and fructose.
c. Examples of other disaccharides include lactose and maltose.
Explanation:
In part a, the formation of the disaccharide sucrose from glucose and fructose involves a condensation reaction. This reaction is also known as a dehydration synthesis reaction, where a molecule of water (H2O) is removed as two monomers, in this case, glucose and fructose, combine to form a larger molecule, sucrose.
The removal of a hydroxyl group (-OH) from one monomer and a hydrogen atom (H) from the other monomer results in the formation of a covalent bond between them, creating the disaccharide. The lost hydrogen and hydroxyl combine to form a water molecule.
Moving on to part b, the chemical reaction that formed sucrose is, as mentioned earlier, a condensation reaction. Condensation reactions are characteristic of the synthesis of various biological molecules, including disaccharides, polysaccharides, and proteins. In this specific case, the condensation reaction between glucose and fructose results in the formation of the disaccharide sucrose.
Finally, in part c, some examples of other disaccharides are lactose and maltose. Lactose is composed of glucose and galactose monomers and is commonly found in milk and dairy products. Maltose, on the other hand, consists of two glucose monomers and is produced during the digestion of starch. Disaccharides play crucial roles in energy storage and transport within living organisms and are essential components of our diet.

Final answer:
Dehydration synthesis is the reaction that forms a disaccharide like sucrose, by removing water from glucose and fructose monomers. This process allows monomers to form a bond and create a disaccharide. Other disaccharides include lactose and maltose.
Explanation:
The reaction that forms the disaccharide sucrose from glucose and fructose monomers is known as dehydration synthesis. During this process, a hydrogen atom from one monomer (glucose/fructose) and a hydroxyl (OH) group from another monomer combine to form a water (H2O) molecule. This removal of water allows a bond to form between the two monomers, creating a disaccharide, in this case, sucrose. Disaccharides are a type of carbohydrate that consist of two monosaccharides linked together.
Other examples of disaccharides include lactose (formed from glucose and galactose) and maltose (formed from two glucose molecules).
