Answer:
The correct answer is d. Metabolism
Step-by-step explanation:
Metabolism is a series of chemical reactions that are interconnected with each other. Metabolites are the compounds that are involved in a metabolism process. Metabolism consists of all the chemical process that occurs in a cell of the body of an organism.
Metabolism consists of two pathways, anabolic pathway, and catabolic pathway. In anabolic pathway synthesis of a larger molecule occurs from smaller molecules like the formation of glucose from CO₂ and H₂O during photosynthesis.
In catabolism, oxidative breakdown of these large molecules into smaller molecules takes place like conversion of glucose into CO₂ and H₂O during respiration.
Therefore the metabolism of an organism is defined as all the chemical processes that occur in the cells of that organism.
