Carbohydrates are commonly found in which of the following foods?

​ ​

• bread and pasta

• chicken and eggs

• beef
• butter and oil
• corn

Which of the following is a monosaccharide that makes up carbohydrates?

• Glucose

• Sucrose

What does a positive test for catalase enzyme in a tissue sample look like?

• The formation of oxygen bubbles

• The solution turns blue

• The tissue sample dissolves completely

• The temperature of the solution increases rapidly

Why is the enzyme catalase important for cellular processes?

• It produces glucose for energy.

• It breaks down toxic hydrogen peroxide into harmless substances.

• It helps in the synthesis of proteins.

• It converts oxygen into carbon dioxide.

Why does a denatured enzyme fail to catalyze a reaction with its substrate?

• The substrate is no longer complementary to the changed active site.

• The substrate is destroyed by the enzyme.

• The enzyme becomes inactive due to lack of energy.

• The enzyme and substrate dissolve in water.
