Metabolic pathway analysis

Definition

Metabolic pathway analysis is the study of the series of chemical reactions that occur within a cell, which are responsible for the conversion of substrates into products necessary for cellular function and metabolism. This type of analysis helps in understanding how different biochemical pathways are interconnected and how they influence plant growth, development, and responses to environmental changes.
