kolezko [41]

Complete question:

¿Cual de los siguientes solutos que pueden estar presentes en el liquido extracelular es transportado de acuerdo al modelo de mecanismo propuesto en la ilustracion?

A) Etanol.

B) Calcio.

C) Glucosa.

D) Estrógeno.

E) Oxígeno.

<em>Nota: La ilustración se encuentra como un archivo adjunto.</em>

Answer:

Ión Calcio y Estrógeno son transportados por proteinas canal a traves de la membrana.      

Explanation:

Durante el paso de sustancias al interior o exterior de la celula ocurren dos tipos de transportes. Transporte activo y pasivo. El primero requiere de energia ya que se produce en contra de un gradiente electroquímico. El segundo, por otra parte, no requiere de energía ya que sucede a favor del gradiente electroquimico.

  • El transporte activo es mediado por proteinas transportadoras que actúan como bombas transportadoras.
  • El transporte pasivo puede ocurrir por
  1. difusión simple a traves de la bicapa lipídica (sin ningunaproteina que medie su paso),
  2. difusión facilitada a traves de proteinas canales (estas proteinas tienen forma de poro hidrofílico y permiten el paso de sustancias de un lado al otro de la membrana celular sin sufrir modificaciones. Permiten el pasaje de iones actuando como canales ionicos y de hormonas o neurotransmisores),  
  3. o difusión facilitada a través de proteinas transportadoras o carriers (estas proteinas son altamente selectivas y sufren un cambio temporal en su conformación al hacer pasar una sustancia de un lado al otro de la membrana plasmatica).    

<em>La ilustración adjuntada muestra un ejemplo de </em><em>proteina de canal</em><em> facilitando el transporte de distintas sustancias.</em>

A) Etanol.  Transporte pasivo. Difusión simple a traves de la bicapa lipídica.    

B) Ion Calcio, Ca²⁺.  Transporte pasivo. Difusión facilitada a traves de proteina canal.

C) Glucosa.  Transporte pasivo. Difusión facilitada a traves de proteina transportadora o carrier.

D) Estrógeno.  Transporte pasivo. Difusión facilitada a traves de proteina canal.

E) Oxígeno. Transporte pasivo. Difusión simple a traves de la bicapa lipídica.

GTPases serve in many signal transduction pathways and the presence of GTP or GDP dictates where the pathway is on or off, respe
Anton [14]

Answer:

None of the above.

Explanation:

GTPases are the regulatory proteins that are involved in the signal transduction pathway involving the activation of the G protein. The mutation in these proteins cal lead to cancer cells.

The guanine nucleotide exchange factors (GEF) allows the replacement of GDP by GTP. They activates the GTPase activity of the cell and can also activate the multiple GTPase activity of the cell. The Ras superfamily is activated by the GEF.

Thus, the correct answer is option (d).
