Exploring Enzymes Through Mr. W's Song

What is the primary role of enzymes in organisms?

• To act as catalysts in metabolic reactions

• To store genetic information

• To transport oxygen

• To provide structural support

Where in the body can enzymes be found?

• Only in the stomach

• Only in the brain

• In the mouth, stomach, and intestines

• Only in the liver

What is the term for the molecule that an enzyme acts upon?

• Inhibitor

• Product

• Reactant

• Substrate

How do enzymes speed up chemical reactions?

• By changing the pH

• By increasing the temperature

• By lowering the activation energy

• By providing energy

What happens to an enzyme if its shape changes?

• It becomes a substrate

• It speeds up reactions

• It stops functioning properly

• It becomes more efficient

What is the optimal pH for enzyme activity?

• Always pH 7

• It varies for each enzyme

• Always pH 9

• Always pH 2

What effect does high temperature have on enzymes?

• Increases their activity indefinitely

• Makes them more stable

• Has no effect

• Denatures them, destroying their activity

Why is a high fever dangerous in terms of enzyme activity?

• It has no effect on enzymes

• It increases enzyme activity too much

• It makes enzymes more efficient

• It can denature enzymes, altering their function

What happens if someone lacks the enzyme lactase?

• They produce more glucose

• They can digest lactose normally

• They cannot digest lactose properly

• They become more efficient at digesting lactose

What are some diseases caused by inherited enzyme deficiencies?

• Arthritis and osteoporosis

• Asthma and allergies

• Galactosemia and PKU

• Diabetes and hypertension
