B
The web of all enzyme-catalyzed reactions in a cell or organism.
C
The web of all chemical reactions in a cell or organism.
D
The web of all endergonic reactions in a cell or organism.
Explanation: 

Detailed explanation-1: -Metabolism is the web of all the enzyme-catalysed reactions in a cell or organism. Anabolism is the synthesis of complex molecules from simpler molecules including the formation of macromolecules from monomers by condensation reactions.

Detailed explanation-2: -All chemical reactions inside the living cell need a catalyst that can help in increasing the rate of the chemical reaction. Enzymes inside our bodywork as a catalyst. Thus, enzymes also help in increasing and decreasing the metabolism process inside our body.

Detailed explanation-3: -The totality of an organism’s chemical reactions is called metabolism. Metabolism is an emergent property of life that arises from interactions between molecules within the orderly environment of the cell. The chemistry of life is organized into metabolic pathways.
