Asi todas las células son muy pequeñas. ¿Qué limitaciones físicas y metabólicas determinan el tamaño celular? ¿ A qué problemas
N76 [4]

Answer:

- Limitación física: la relación superficie volumen es baja para un intercambio eficiente de sustancias con el medio

- Limitación metabólica: en principio no existen limitaciones metabólicas  

Explanation:

La membrana celular es una estructura fundamental para el funcionamiento celular, ya que de la membrana celular depende el intercambio de nutrientes y desechos por parte de la célula con su entorno (medio extracelular). En células muy grandes la relación entre la superficie cubierta por la membrana y el volumen celular es muy baja, lo cual dificulta el intercambio de compuestos (tanto nutrientes como desechos) con el medio extracelular. Por otro lado, los mecanismos metabólicos en principio no deberían verse afectados por el tamaño celular. Por ejemplo, los perfiles metabólicos de expresión génica son independientes del tamaño celular y están adaptados a diferentes tipos celulares, desde una célula huevo que es proporcionalmente varias veces más grande que un célula diferenciada la cual sin embargo no ha perdido la capacidad de dividirse, un ejemplo de esto son las células cancerosas derivadas de células epidérmicas diferenciadas las cuales poseen la capacidad de dividirse y de proliferar indiscriminadamente.

A number of mutations have been described in the G protein Ras that have profound effects on its activity. For example, some mut
gladu [14]

Answer:

a mutation that blocks the GTPase activity of Ras

Explanation:

A G protein in inactive state is GDP bound but as soon as a guanine exchange factor (GEF) exchanges it with GTP it gets activated which means that in GTP bound state it is active. G - protein has endogenous GTPase activity. Upon interaction of GAP, the GTPase activity of this protein is exhibited. When GAP is present, hydrolysis of GTP into GDP occurs which leads to inactivation of G protein. A mutation which will block GTPase activity of Ras will therefore result in constitutive active signaling even in the absence of ligand binding to it's receptor. In such scenario, GTP will not be hydrolyzed into GDP so signaling will be up-regulated.

How are the chromosomes arranged DIFFERENTLY in Metaphase I (meiosis) compared to Metaphase during mitosis?
jasenka [17]

Answer:

tetrads align on the metaphase plate. In metaphase of mitosis, individual chromosomes align there. ... In meiosis there are two successive divisions, ultimately producing four daughter cells. In mitosis, there is only one division and it produces two daughter cells.

You will have to expand more on this but I think it is helpful to make things more efficient to what we need them for and it could make a positive impact in that way but also negative impacts could be deformities or diseases by changing some things genetic makeup
