Detailed explanation-1: -decomposition reaction. Decomposition reactions are characterized by a larger molecule (e.g. starch) being broken down into smaller molecules (e.g. glucose) as a catabolic reaction.
Detailed explanation-2: -When the body’s digestive system breaks down starch (a complex carbohydrate) into simpler carbohydrates, the reaction is an example of a catabolic reaction resulting in the release of stored chemical energy. Therefore, the correct answer is C. catabolic and results in the release of energy.
Detailed explanation-3: -Figure 2 demonstrates the breakdown of starch into glucose, an example of a catabolic reaction. Figure 2: A diagram showing the breakdown of amylose (a form of starch) into its component glucose molecules. This process releases energy in the form of ATP and is an example of a catabolic reaction.
Detailed explanation-4: -An example of a catabolic reaction is the breakdown of starch in carbohydrate-rich foods into simple sugars like glucose. The breaking of bonds in the large starch molecules is what releases energy.
Detailed explanation-5: -The long polysaccharide starch is broken down (hydrolyzed) by the enzyme amylase. The products are glucose molecules (a monosaccharide) and maltose (a disaccharide). These smaller sugars are small enough that a bacterial cell could transport them inside.
