What is metabolic pathway in plants?

Chemical reactions in the cell occur in a sequence of stages called a metabolic pathway. Each stage is catalyzed by an enzyme, a protein that changes (usually increases) the rate at which the reaction proceeds but does not alter the reactants or end products.

plant metabolic processes:

Plant metabolism is defined as the complex of physical and chemical events of photosynthesis, respiration, and the synthesis and degradation of organic compounds. … This primary metabolism consists of chemical reactions that allow the plant to live.
