Question

Enzymes accelerate the speed of biochemical reactions by:

A.

Providing additional energy

B.

Increasing number of substrate molecules

C.

Breaking chemical bonds

D.

Lowering activation energy

Correct option is D

The Correct Answer is: (D) Lowering activation energy
Explanation:
Enzymes accelerate biochemical reactions by lowering the activation energy required for the reaction to proceed. Activation energy is the minimum energy needed for a reaction to occur, and enzymes work by reducing this energy barrier. 
Lowering activation energy: By lowering the activation energy, enzymes allow reactions to occur faster and with less energy input, making them essential for the proper functioning of metabolic processes in living organisms.
Information Key Points:
  • Enzymes act as biological catalysts, facilitating reactions without being consumed in the process.

  • The lower activation energy provided by enzymes speeds up reactions and allows organisms to carry out essential biochemical processes efficiently.​
