Question

The enzyme phosphorylase converts starch into soluble sugars at pH ________.
a) 5 b) 7
c) 6 d) 8

Answer 1

The enzyme phosphorylase converts starch into soluble sugars at pH 8.

An enzyme in your saliva called amylase breaks down starch into glucose, a type of sugar.

Answer 2

The enzyme phosphorylase converts starch into soluble sugars at pH is (d) 8.

Explanation:

• An amylase is an enzyme that catalyses the hydrolysis of starch into sugars.
• Amylase is present in the saliva of humans and some other mammals, where it begins the chemical process of digestion.
• The enzymes that break down or hydrolyze starch into the constituent sugars are known as amylases.
• Amylases are found in plants and in animals.
• pH is a measure of acidic or basic water.
• pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
• PH is a quantitative measure of the acidity or basicity of aqueous or other liquid solutions.
• Amylase any member of a class of enzymes that catalyze the hydrolysis (splitting of a compound by addition of a water molecule) of starch into smaller carbohydrate molecules such as maltose (a molecule composed of two glucose molecules).
