why do polysaccharides like cellulose and peptidoglycan able to resist degradation and enzymatic activity
mixer [17]

Polysaccharides like Cellulose form insoluble micro-fibrils making it resistant to degradation and enzymatic activity.

<u>EXPLANATION: </u>

  • Polysaccharides components in general broken down monosaccharides and they are very little enough to be absorbed by the body.
  • But the polysaccharide like cellulose cannot be absorbed by our body.
  • Cellulose is made up of simple polymers that form insoluble micro-fibrils results in resistant to degradation and enzymatic activity.

En los seres vivos acuaticos el oxigeno es tomado del __________ y penetra a la celula por el fenomeno de ___________
andrezito [222]

Answer:

En los seres vivos acuáticos el oxigeno es tomado del <u><em>agua</em></u> y penetra a la célula por el fenómeno de <em><u>respiración branquial.</u></em>

Explanation:

La respiración es el proceso mediante el cual los seres vivos obtienen oxígeno.  Es decir, la respiración implica el reemplazo del dióxido de carbono en los pulmones por oxígeno del aire, y puede ser pulmonar, branquial, traqueal o cutánea.

La respiración branquial es un tipo de respiración propia de la mayoría de los animales acuáticos y se lleva a cabo en las branquias, unas estructuras con forma de láminas que contienen vasos sanguíneos. Los animales acuáticos dispone de estos órganos que permiten absorber el oxígeno que se encuentra en el agua y eliminar el dióxido de carbono.

El agua que entra por la boca y circula por las branquias, donde el oxígeno es absorbido, pasa a la sangre y es transportado a todo el cuerpo donde se produce una respiración celular.

Es decir, <em><u>en los seres vivos acuáticos el oxigeno es tomado del agua y penetra a la célula por el fenómeno de respiración branquial.</u></em>
