Question

A solution of starch at room temperature does not readily decompose to form a solution of simple sugars because:

A) Starch molecules are too large to undergo decomposition.

B) Starch is a stable compound.

C) Enzymes needed for starch decomposition are not present.

D) Room temperature is not conducive to starch decomposition.

Answer 1

A solution of starch at room temperature does not readily decompose to form a solution of simple sugars because enzymes needed for starch decomposition are not present.

Step-by-step explanation:

A solution of starch at room temperature does not readily decompose to form a solution of simple sugars because enzymes needed for starch decomposition are not present.

Starch is a complex carbohydrate made up of glucose monomers joined by glycosidic linkages. In the human body, amylases are enzymes that degrade starch into usable glucose units. However, when starch is in a solution, the necessary enzymes are not present to catalyze the decomposition of starch into simple sugars.

This lack of enzymes prevents the breakdown of starch at room temperature, leading to its stability without readily forming a solution of simple sugars.
