metabolic pathway

Explanation:

A metabolic pathway is a chain of biochemical reactions in a cell that yield intermediate products (known as metabolites) before the final product is achieved. Usually the product of one enzyme in the chain is the substrate of the next enzyme. Examples of metabolic pathways are Glycolysis and Krebs cycles. The illustration below (attached) shows the enzymes involved in Glycolysis metabolic pathway.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
