Cells of the nervous system sometimes secrete chemical messengers instead of neurotransmitters. These specialized nervous system cells are called neurosecretory cells, and they produce neurosecretions. Every nerve cells are long, thin cylinders along which electrical disturbances (nerve impulses) travel. the cell membrane of a typical nerve cell consists of an inner and an outer wall separated by a distance of 0.10 μm and the electric field within the cell membrane is 7.0×105n/c.

Las bacterias están presentes en todos los alimentos ¿Qué ocurrirá con su metabolismo si refrigeramos o congelamos el alimento?
kozerog [31]

Answer:

Si refrigeramos o congelamos el alimento, las bacterias presentes en ellos tendrán un metabolismo más lento, incluso llegando al punto de la muerte por encima de temperaturas a las cuales no les es posible vivir. Es importante mantener la cadena de frío para que las bacterias no tengan lugar a su reproducción.

Explanation:

Las distintas bacterias que pueden estar presentes en los alimentos tienen distintos parámetros que hacen que sea posible su vida y reproducción. En cuanto a la temperatura, es un factor muy importante ya que podemos encontrar bacterias termolábiles o termoresistentes según puedan vivir en las variaciones de temperatura. La mayoría de ellas no resiste temperaturas frías de refrigeramiento o congelamiento, motivo por el cual los alimentos se conservan así. De esta forma reducimos el riesgo de padecer Enfermedades de Transmisión Alimentaria. La cadena de frío por su parte permite que esa temperatura sea constante a lo largo de todo el procesamiento, transporte y disposición de los alimentos.
