Cofactor - Chemistry Encyclopedia - structure, reaction, …

Phosphofructokinase is an example of a metal-activated enzyme, which alyzes the reaction fructose-6-phosphate + ATP → fructose-1,6-bisphosphate + ADP A divalent metal ion (Mg 2+ ) is needed to coordinate the phosphate groups on the ATP molecule in order for phosphofructokinase to successfully alyze this reaction.

Do ionic bonds occur between metal and non-metal …

Ionic bonds occur between anions and ions. And ions may be metallic, i.e., #M^(2+)#, or they may be non-metallic, i.e. ammonium salts, #NH_4^+#.And anions, while typically non-metallic, i.e. #X^-# #"(X = F, Cl, Br)"#, may be metallic, i.e. #Cr_2O_7^(2-)#, or #MnO_4^-#, or at least containing a metal centre.

The Parts of the Periodic Table - Angelo State University

In general, metal and nonmetals coine to form ionic compounds, while nonmetals coine with other nonmetals to form covalent compounds (molecules). Since the metals are further to the left on the periodic table, they have low ionization energies and low electron affinities , so they lose electrons relatively easily and gain them with difficulty.
