B) A series of chemical reactions where enzymes work one at a time to convert a reactant into intermediates and the intermediates into a final product.
Explanation:
In our cells there are multiple chemical reactions happening all the time to convert the elements we ingest (food, water, air) into the products the organism needs.
This processes can be very complex and offen involves various reactions (steps). Also, many of this reactions need to by catalized by enzymes in order to happen.
A metabolic pathway is series of chemical reactions that are well organized, well co-ordinated, and purposeful manner; all these reactions are collectively called as metabolism.
Metabolic Pathways this is a series of biochemical reaction where enzymes work one at a time to convert a reactant into intermediates and the intermediates into a final product. The product of reactions serve as an a reactants for the next enzymatic reaction.
The reactants, intermediates, products of an enzymatic reaction are known as metabolites.
The method used for measuring the small distance is by using the scales and the distance measured over long distance is by inch tape or measuring tape.
