Understanding Amylase and Its Optimal pH

What is the primary function of the enzyme amylase?

• To break down proteins

• To synthesize starch

• To convert sugars into starch

• To break down starch

During the experiment, what indicates that starch is present?

• The solution turns blue or black

• The solution remains clear

• The solution turns red

• The solution turns green

What is the purpose of adding iodine to the dimple tray in the experiment?

• To neutralize the pH

• To indicate the presence of starch

• To provide a source of starch

• To speed up the reaction

What does the graph of time against pH help determine in the experiment?

• The concentration of iodine

• The temperature of the reaction

• The optimal pH for amylase activity

• The amount of starch used

What happens to the enzyme amylase when the pH is far from its optimum level?

• It denatures and loses its function

• It starts producing starch

• It becomes more active

• It changes color
