Synthesis (anabolic) reaction
B
Decomposition (hydrolysis) reaction

Oxidation-reduction (redox) reaction
D
Acid-base neutralization reaction
검증된 단계별 안내1
Step 1: Understand the types of chemical reactions involved in biological processes. Synthesis (anabolic) reactions build larger molecules from smaller ones, while decomposition reactions break down larger molecules into smaller components.
Step 2: Recognize that starch is a large polysaccharide made up of glucose units linked together, and digestive enzymes break it down into simpler sugars.
Step 3: Identify that the breakdown of starch involves splitting the bonds between glucose units, which is characteristic of a decomposition reaction.
Step 4: Note that this breakdown specifically involves the addition of water molecules to cleave the bonds, a process known as hydrolysis.
Step 5: Conclude that since the reaction breaks down starch into smaller molecules using water, it is classified as a decomposition (hydrolysis) reaction rather than synthesis, redox, or acid-base neutralization.
