Chains of enzyme reactions that break down or build molecules are called pathways. atp energy metabolic sensory

Metabolic
Metabolic pathways begin with a specific molecule, which is then altered in a series of steps that ultimately results in a particular product. Each step in a metabolic pathway is catalyzed by a specific enzyme.

Explanation:

A strip of solid palladium metal is put into a beaker of nicl2

Palladium (Pd) + Nickel Chloride (NiCl2)

To answer this question properly you must refer to the reactivity series.

The activity series is a chart of metals listed in order of declining relative reactivity. The top metals are more reactive than the metals on the bottom.

In this series, Nickel is higher than Palladium. This means that if a Palladium strip is placed into a solution of a Ni salt, then a reaction will not take place, nothing would happen.

Because Pd is lower than Ni in the reactivity series.

There is no reaction so no equation.
