Biological catalysts involved in the rate of chemical reactions are called enzymes

In the human body, various chemical reactions occur inside the cell or outside the cell

The goal is to get the energy needed for the body's metabolic processes. Metabolism itself is divided into two, namely anabolism (formation process) and catabolism (decomposition process)

Chemical reactions that occur can be influenced by various factors such as temperature, concentration, or surface area of the substance that reacts.

Chemical reactions in the body can take place quickly because of the role of Enzymes.

Actually, without enzymes, chemical reactions can take place but run slowly

The enzyme itself can be divided into two major components, namely protein, and non-protein

So the function of the enzyme is as a catalyst because it lowers activation energy

Factors that influence the work of enzymes include:

The enzyme works optimally in a temperature range of 30-40 C to prevent damage so that the enzyme is inactive

Comparison of enzyme concentration and catalyst substrate must be suitable so that there are no residual non-catalyzed substances

Enzymes are damaged if they are too strong or acidic

beyond the specified pH, the enzyme's work will be inhibited so that enzyme activity decreases

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
