What role do active enzymes play in metabolic pathways?

Active enzymes play a crucial role in metabolic pathways by facilitating biochemical reactions efficiently. Enzymes are biological catalysts that accelerate the rate of reactions by lowering the activation energy required for the reaction to proceed. This increased efficiency allows cells to carry out necessary reactions at a much faster rate, which is essential for maintaining life and metabolic homeostasis.

In metabolic pathways, where a series of biochemical reactions occur, enzymes help transform substrates into products through specific interactions. Each enzyme is typically specific to a particular substrate, ensuring that metabolic processes are regulated and occur in a concerted fashion. This specificity and efficiency are vital for processes such as digestion, energy production, and the synthesis of biomolecules.

In contrast, the other options highlight processes that are not directly related to the function of active enzymes in metabolism. Enzymes do not break down cell membranes; instead, that role is typically played by other classes of molecules such as detergents or specific membrane proteins. Additionally, while genetic information is indeed vital for cellular function and is stored in DNA, this is not a role played by enzymes. Lastly, enzymes do not inhibit metabolic processes but rather promote and facilitate them; when needed, regulatory mechanisms may lead to inhibition in specific contexts, but this is done by other regulatory molecules and
