Role of Alpha-Amylase in Carbohydrate Metabolism

Hard Biochemistry Carbohydrates

In the context of carbohydrate metabolism, the enzyme alpha-amylase plays a critical role in the breakdown of polysaccharides into simpler sugars. This enzyme is present in both saliva and the pancreas, where it initiates the digestion of carbohydrates. Understanding the biochemical pathway of carbohydrate metabolism is essential for grasping how energy is harvested from dietary sugars.

Which of the following statements accurately describes the role of alpha-amylase and its activity on carbohydrates?

Alpha-amylase hydrolyzes alpha-1,6-glycosidic bonds in polysaccharides.

Alpha-amylase is secreted by the stomach and converts glycogen directly into glucose.

Alpha-amylase acts primarily on starch and glycogen, breaking them down into maltose and dextrins.

Alpha-amylase preferentially targets cellulose, leading to the release of glucose.
