L9 Bio Homework

What term describes the process where an enzyme's active site changes shape slightly to bind more tightly to its substrate?

• Denaturation

• Catalysis

• Induced fit

• Hydrolysis

What is the primary function of enzymes in biological reactions?

• To slow down reactions

• To act as structural components of cells

• To speed up reactions without being consumed

• To store genetic information

What happens to lactose in individuals who are lactose intolerant?

• It is broken down into smaller parts by excess lactase.

• It remains undigested due to insufficient lactase.

What happens to an enzyme if its environment changes significantly outside its ideal pH or temperature range?

• It becomes more efficient at catalyzing reactions.
