Understanding Enzymes

What is the primary function of enzymes?

• To produce energy

• To slow down chemical reactions

• To speed up chemical reactions

• To change the color of substrates

What is the active site of an enzyme?

• The part of the enzyme that changes color

• The part of the enzyme that stores information

• The part of the enzyme that produces energy

• The part of the enzyme that binds to substrates

What is a substrate in the context of enzymes?

• A type of enzyme

• A molecule that binds to the enzyme's active site

• A type of protein

• A byproduct of enzyme reactions

What happens to an enzyme when it becomes denatured?

• It speeds up its activity

• It multiplies

• It changes its shape and stops working

• It becomes more efficient

What is the role of lactase in the body?

• To build up lactose

• To break down lactose

• To produce lactose

• To store lactose

What suffix is commonly found at the end of enzyme names?

• -ine

• -ase

• -ose

• -ite

What is lactose?

• A lipid

• A type of enzyme

• A protein

• A disaccharide sugar

What is the function of cofactors and coenzymes?

• To change the color of enzymes

• To help enzymes build up or break down substrates

• To inhibit enzyme activity

• To store energy for enzymes

What happens when an enzyme's environment changes out of its ideal pH or temperature range?

• The enzyme becomes more active

• The enzyme multiplies

• The enzyme becomes denatured

• The enzyme changes color

What is the relationship between enzymes and catalysts?

• Catalysts inhibit enzyme activity

• They are unrelated

• Catalysts are a type of enzyme

• Enzymes are a type of catalyst
