Understanding Enzymes: A Deep Dive

What are enzymes primarily made of?

• Lipids

• Carbohydrates

• Nucleic acids

• Proteins

What is the role of enzymes in chemical reactions?

• To slow down reactions

• To speed up reactions without being consumed

• To act as products in reactions

• To consume substrates

Why are enzymes important for living organisms?

• They provide energy

• They create new cells

• They produce oxygen

• They control chemical reactions

How do substrates and enzymes interact?

• Like a lock and key

• By permanently binding

• Through destruction of the enzyme

• Randomly

What happens to an enzyme after it catalyzes a reaction?

• It gets consumed

• It disintegrates

• It remains unchanged

• It becomes a substrate

What can affect enzyme activity?

• Solubility in water

• Color and shape

• Temperature and pH

• Size and weight

What is the optimal temperature for most human enzymes?

• 0 degrees Celsius

• 22 degrees Celsius

• 37 degrees Celsius

• 100 degrees Celsius

What happens to an enzyme when it is denatured?

• It becomes a substrate

• It is consumed by the reaction

• It changes shape and cannot function

• It works faster

Which enzyme breaks down hydrogen peroxide?

• Pepsin

• Catalase

• Lipase

• Amylase

What is the effect of pH on enzyme activity?

• It can denature the enzyme

• It turns the enzyme into a substrate

• No effect

• It increases the size of the enzyme
