What do we know about the consumption of an enzyme durning a metabolic reaction in the body

An enzyme is not consumed during a metabolic reaction.

An enzyme is an organic catalyst. It speeds up a metabolic reaction but is unchanged at the end of the process.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
