Dehydration Synthesis, Disaccharide
For Plato the answer is (B)
b
When glucose is polymerized to form glycogen or starch, a water molecule is removed during each condensation reaction between glucose molecules. This process is known as dehydration synthesis.
To make sucrose, a molecule of water is removed from glucose and fructose. This dehydration reaction results in the formation of a glycosidic bond between the glucose and fructose molecules, creating sucrose.
In glycolysis, the high-energy electrons removed from glucose are stored in the molecule NADH. During the process, two molecules of NAD+ are reduced to NADH as glucose is broken down into pyruvate. This conversion allows the energy extracted from glucose to be captured and utilized in subsequent cellular respiration processes.
The breaking down of glucose is hydrolysis. In hydrolysis, a water molecule is used to break bonds in a larger molecule, such as glucose, resulting in smaller molecules being formed. Dehydration is the opposite process, where water is removed to form larger molecules from smaller ones.
Water (H2O) molecules, one on either side of the molecule.

Two glucose molecules form a maltose molecule.
O_H and H must be moved. Have a nice day! :P

Glucose is formed in photosynthesis when two molecules are joined together. These two molecules are ATP and CO2 (carbon dioxide).
Dehydration synthesis is a chemical reaction in which a water molecule is removed to bond two molecules together. In the case of joining four glucose molecules to form a polysaccharide, a water molecule is removed from each glucose molecule to form glycosidic bonds between them, resulting in the release of four water molecules.

Maltose is formed when two glucose molecules are bond together. A water molecule is removed in this process. This type of reactions are called condensation reactions.
In order to join multiple glucose molecules together to form larger polysaccharides like starch or glycogen, water molecules must be removed in a condensation reaction. This process involves the removal of a hydroxyl group (-OH) from one glucose molecule and a hydrogen atom (-H) from the other glucose molecule, resulting in the formation of a glycosidic bond between the two glucose units. This dehydration synthesis reaction requires energy input to proceed and results in the release of a water molecule as a byproduct.
