Question

why there is a need for a serics of chemical reactions in the living body​

Answer 1

Answer:

Metabolic reactions are chemical reactions that occur within the body to release useable energy. ... During cellular metabolism, the molecule glucose combines with oxygen and reacts to form carbon dioxide and water, as well as ATP, which is a form of energy that the body can use for its functions ...,,

Answer 2

Answer:

The hu­man body is a unique or­gan­ism that is in close con­tact with the sur­round­ing en­vi­ron­ment. Dur­ing the liv­ing process, nu­mer­ous com­plex chem­i­cal re­ac­tions take place in the hu­man body, in which bi­o­log­i­cal cat­a­lysts take part – en­zymes. We can recre­ate some of these re­ac­tions can our­selves, in the lab­o­ra­to­ry or the home.

Fea­tures of chem­i­cal re­ac­tions tak­ing place in the hu­man body Chem­i­cal re­ac­tions in liv­ing or­gan­isms dif­fer from or­di­nary re­ac­tions in two ways: high ef­fec­tive­ness and com­plex­i­ty of mech­a­nisms. The pro­tein en­vi­ron­ment of­ten leads to the spe­cif­ic and swift trans­for­ma­tion of func­tion­al groups, com­pared with or­di­nary mol­e­cules. Ow­ing to the large size of bi­o­log­i­cal­ly ac­tive mol­e­cules, it is im­pos­si­ble to cal­cu­late the to­tal sur­faces of po­ten­tial en­er­gy and to give pre­cise so­lu­tions for the quan­tum dy­nam­ics of the nu­clei for these mol­e­cules, so it is suit­able to de­vel­op mod­els of in­ter­nal molec­u­lar dy­nam­ics. These mod­els should be sim­ple, in or­der to al­low a rea­son­able nu­mer­i­cal so­lu­tion, but at the same time suf­fi­cient­ly de­vel­oped to re­flect the main as­pects of bio­chem­i­cal trans­for­ma­tions.

One of the main chem­i­cal re­ac­tions that takes place in the hu­man body and sup­ports life ac­tiv­i­ty is me­tab­o­lism – a re­ac­tion car­ried out as by en­zymes. En­zymes are bio­chem­i­cal cat­a­lysts. They are need­ed by the body for nor­mal life ac­tiv­i­ty. No chem­i­cal re­ac­tion in a liv­ing or­gan­ism takes place with­out en­zymes.
