Understanding Enzymes: A Biological Perspective

What do most enzymes consist of?

• Carbohydrates

• Lipids

• Nucleic acids

• Proteins

What is the specific area where substrates bind to an enzyme called?

• Catalytic site

• Active site

• Substrate site

• Binding site

What happens to an enzyme's active site during induced fit?

• It loses its functionality

• It detaches from the enzyme

• It changes shape to bind the substrate perfectly

• It becomes rigid

What is the role of enzymes in biological reactions?

• To speed up reactions

• To stop reactions

• To slow down reactions

• To observe reactions

What condition is caused by a lack of lactase enzyme?

• Lactose intolerance

• Sucrose intolerance

• Glucose intolerance

• Fructose intolerance

Which enzyme breaks down fats?

• Lipase

• Lactase

• Protease

• Amylase

What are cofactors and coenzymes?

• Substrates of enzymes

• Products of enzyme reactions

• Types of enzymes

• Helpers in enzyme action

What is the ideal pH condition for stomach enzymes?

• Slightly acidic

• Very acidic

• Neutral

• Basic

What can cause an enzyme to become denatured?

• Binding with the correct substrate

• Changes in pH or temperature out of the enzyme's ideal range

• The presence of cofactors

• Ideal pH and temperature conditions

Why are enzymes important in medical research?

• They are not important in medical research

• They can cause diseases

• They regulate body processes and can be involved in diseases

• They are used to diagnose diseases
