Introduction to Metabolic Pathways

Metabolic pathways are intricate networks of chemical reactions taking place within biological systems, playing a crucial role in maintaining life. They can be broadly categorized into two types: catabolic pathways, which involve the breakdown of molecules to release energy, and anabolic pathways, which use energy to build complex molecules from simpler ones.

These pathways facilitate various essential processes, including:

Introduction to Enzyme Kinetics

Enzyme kinetics is a fascinating branch of biochemistry that encompasses the study of the rates of enzyme-catalyzed reactions. The kinetic behavior of enzymes is fundamental to understanding how biological systems function and how these biocatalysts interact with substrates to facilitate life-sustaining processes. Essentially, enzyme kinetics provides insights into how enzymes increase the speed of reactions by lowering activation energy, thus playing a crucial role in metabolic pathways.
