Porque los bioelementos y las biomolegulas son importantes para todos los organismos
miss Akunina [59]

Explanation:

Bioelementos

De los más de 100 elementos encontrados en la Tabla periódica, la materia viva está

constituida por unos 70 elementos y solo alrededor de 21, son esenciales para el desarrollo y

conservación de la vida. Estos elementos se llaman bioelementos o elementos biogénicos.

Bioelementos Primarios

Están formados por: C, H, O, N, P y S, los cuales constituyen alrededor

del 96.2% de la materia viva en base seca. Son los componentes

fundamentales de las biomoléculas. Son iimprescindibles para formar:

carbohidratos, lípidos, proteínas y ácidos nucleicos.

Clasificación de

los bioelementos

Bioelementos Secundarios

Grupo comprendido por los iones: Na+

, K+

, Ca2+, Mg2+, Cl-

. Estos

elementos aunque se encuentran en menor proporción que los

primarios, también son indispensables para los seres vivos. En medio

acuoso (solvente presente en células tejidos y órganos), siempre se

encuentran ionizados.

Oligoelementos

Son aquellos bioelementos que se encuentran en los seres vivos en un

porcentaje menor del 0.1%. Algunos, los indispensables, se encuentran

en todos los seres vivos, mientras que otros, variables, solamente los

necesitan algunos organismos. En este grupo se encuentran: Fe, Cu,

Zn, Mn, I, Ni y Co (que aparecen en la mayoría de los organismos) y Si,

F, Cr, Li, B, Mo y Al (sólo están presentes en grupos concretos).

Constituyen menos del 0.1% y son esenciales para desempeñar

procesos bioquímicos y fisiológicos.
