What is role of enzymes in metabolism?

 Enzymes act as biological catalysts in metabolism, facilitating chemical reactions necessary for cellular processes. They accelerate these reactions by lowering the activation energy required for them to occur, enabling metabolic pathways to proceed at biologically relevant rates. Enzymes also ensure specificity, guiding substrates to their appropriate reactions and preventing side reactions. Overall, enzymes play a fundamental role in regulating metabolic pathways, maintaining cellular homeostasis, and supporting life processes.

What is metabolism?

Metabolism refers to the set of biochemical processes that occur within living organisms to sustain life. It involves the conversion of nutrients from food into energy and building blocks for cellular components. Metabolism encompasses two main processes: catabolism, where larger molecules are broken down into smaller ones to release energy, and anabolism, where smaller molecules are synthesized into larger ones using energy. These processes collectively regulate the production and utilization of energy, as well as the synthesis and breakdown of molecules necessary for cellular functions, growth, and maintenance.

What is anabolism?

Anabolism is the set of metabolic pathways that involve the synthesis of complex molecules from simpler ones. It requires energy input to build larger molecules, such as proteins, carbohydrates, lipids, and nucleic acids, from smaller building blocks. Anabolic processes are essential for growth, repair, and maintenance of cells and tissues. They involve the assembly of molecules through dehydration synthesis or condensation reactions, where water is removed to form bonds between smaller molecules. Overall, anabolism promotes the buildup of biomolecules, contributing to the overall growth and functioning of organisms.
