Pathway mapping

Definition

Pathway mapping is a systematic approach used to identify and visualize the biological pathways and interactions that occur within an organism. This technique helps researchers understand the complex networks of molecular interactions, signaling cascades, and metabolic processes that are crucial for cellular function and response to environmental changes. By mapping these pathways, scientists can better comprehend how various components of a biological system interact and contribute to overall physiological processes.
