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.

IONIC BONDING Name Ionic bonding occurs when a metal …
IONIC BONDING Name Ionic bonding occurs when a metal transfers one or more electrons to a nonmetal in an effort to attain a stable octet of electrons, For example, the transfer of an electron from sodium to chlorine can be depicted by a Lewis dot diagram.
IB Chemistry standard level notes: Ionic bonding
The non-metal atoms (in this case chlorine) receive electrons (from the metal atoms) into their outer shells making the outer shell full, a negatively charged ion is formed. Notice that the ending of the particle is now changed to -ide.

Calcium Metal | AMERICAN ELEMENTS
Calcium Metal is available as disc, granules, ingot, pellets, pieces, powder, rod, wire, and sputtering target. Ultra high purity and high purity forms also include metal powder, submicron powder and nanoscale, quantum dots, targets for thin film deposition, pellets for evaporation and single crystal or polycrystalline forms.
Calcium Carbonate - University Of Illinois
Calcium carbonate, CaCO 3 Calcite is one of the most abundant of the non-silie minerals. Pure calcium carbonate is colorless but, because it dissolves in acidic water and can recrystallize with different inclusions, calcite has many forms and colors in nature.

Calcium | Ca (Element) - PubChem
The metal has a silvery color, is rather hard, and is prepared by electrolysis of fused chloride and calcium fluoride (to lower the melting point). Chemically it is one of the alkaline earth elements; it readily forms a white coating of nitride in air, reacts with water, burns with a yellow-red flame.

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.
