Role of Enzymes in Metabolism

Enzymes play a pivotal role in metabolism, which is a key topic in the Class 11 NCERT Biology textbook. They act as biological catalysts and speed up chemical reactions without being consumed in the process. Here are some roles of enzymes in metabolism:

• Specificity: Each enzyme is specific to a particular reaction or type of reaction.
• Lowering Activation Energy: Enzymes lower the activation energy needed for reactions, making them occur faster.
• Regulation: Enzymes help regulate metabolic pathways by being activated or inhibited as needed.
• Reusability: Enzymes are not used up in reactions, allowing them to catalyze multiple rounds of reactions.

Understanding enzymes is fundamental to comprehending how metabolic processes are controlled and maintained in living organisms.
