What is the primary role of enzymes in biological processes?

• To accelerate chemical reactions

• To be consumed in reactions

• To slow down reactions

• To increase activation energy

Which environmental factor does NOT influence enzyme activity?

• Temperature

• pH

• Reactant concentration

• Light intensity

What happens to enzymes at extreme temperatures or pH levels?

• They become more efficient

• They denature

• They replicate faster

• They change substrates

What is the function of the active site of an enzyme?

• To bind substrates and form an enzyme-substrate complex

• To denature the enzyme

• To increase the enzyme's temperature

• To act as a cofactor

Which of the following is NOT a way enzymes are regulated?

• Presence of cofactors

• Competitive inhibition

• Noncompetitive inhibition

• Increasing substrate concentration
