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

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.

• It is converted into a different type of sugar.

• It is absorbed directly into the bloodstream as a disaccharide.

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

• It becomes more efficient at catalyzing reactions.

• It undergoes denaturation, losing its shape and function.

• It starts catalyzing different types of reactions.

• It forms stronger bonds with its substrate.
