The Role and Function of Enzymes in Biological Systems

What is the primary role of enzymes in biological systems?

• To act as catalysts and accelerate chemical reactions

• To provide energy for biochemical reactions

• To be consumed in biochemical reactions

• To store genetic information

How do enzymes achieve specificity in the reactions they catalyze?

• By having a unique shape that fits specific molecules

• By being consumed in the reaction

• By providing energy to the reaction

• By changing their shape to fit any molecule

What is the significance of enzymes lowering the activation energy of reactions?

• It allows reactions to occur more easily and quickly

• It increases the energy required for reactions

• It stops reactions from occurring

• It consumes the enzyme in the process

What happens to enzymes after they facilitate a reaction?

• They return to their original state and can be reused

• They are consumed and cannot be reused

• They change shape permanently

• They become inactive

Which of the following is NOT a function of enzymes?

• Storing genetic information

• Acting as catalysts

• Lowering activation energy

• Facilitating specific reactions
