Exploring Lactase Enzyme Functions and Applications

What was the initial observation of the test strips?

• They changed color.

• They dissolved in the milk.

• They broke into pieces.

• They remained the same color.

What was observed in the control group?

• The test strip turned brown.

• There was no color change.

• The test strip dissolved.

• The test strip turned green.

What was added to the milk in experimental group A?

• Salt

• Sugar

• Lactate

• Water

What was the difference in the treatment of lactate in experimental group B?

• It was mixed with water.

• It was microwaved.

• It was left in the sun.

• It was frozen.

What was the result of microwaving the lactate in experimental group B?

• It increased the efficiency of lactate.

• It changed the efficiency of lactate.

• It made the lactate dissolve.

• It had no effect on the lactate.

What was detected in the milk with regular lactate added?

• Glucose

• Fructose

• Sucrose

• Lactose

What does the presence of glucose in the milk indicate?

• The milk was spoiled.

• The enzyme digested the lactose.

• The milk was too fresh.

• The milk was too old.

What are the monomers that lactose is split into?

• Glucose and fructose

• Galactose and sucrose

• Glucose and galactose

• Fructose and sucrose

What is the main ingredient in lactaid responsible for digesting lactose?

• Lactase enzyme

• Lactose

• Galactose

• Glucose

What happens to lactose when it is digested by lactase enzyme?

• It evaporates.

• It becomes solid.

• It splits into glucose and galactose.

• It turns into water.
