Understanding Enzymes and Their Functions

What is the role of the active site in an enzyme?

• To denature the enzyme

• To store energy for the enzyme

• To produce cofactors

• To bind substrates specifically

What is the term used to describe the enzyme's ability to speed up reactions?

• Catalysis

• Hydrolysis

• Synthesis

• Denaturation

Which of the following is an example of an enzyme?

• Sucrose

• Glucose

• Lactase

• Lactose

What happens to an enzyme when it becomes denatured?

• It produces more cofactors

• It binds more substrates

• It speeds up its activity

• Its shape becomes distorted

What is the function of lactase in the digestive system?

• To build up proteins

• To break down lactose

• To synthesize lipids

• To denature other enzymes

What is a common suffix for enzymes?

• -ase

• -ate

• -ose

• -ine

What are cofactors and coenzymes?

• Substrates for enzymes

• Helpers for enzymes

• Products of enzyme reactions

• Types of enzymes

What is lactose classified as?

• A monosaccharide

• A protein

• A disaccharide

• A polysaccharide

What is the result of an enzyme-substrate reaction?

• A new enzyme

• A cofactor

• A product

• A denatured enzyme

What is the effect of temperature and pH on enzyme activity?

• They convert products back to substrates

• They can denature the enzyme

• They have no effect

• They increase substrate concentration
