<h2>Answer: Differentiation from visibly undifferentiated precursor cells occur during embryonic development, during metamorphosis of larval forms, and following the separation of parts in asexual reproduction. It also takes place in adult organisms during the renewal of tissues and the regeneration of missing parts. </h2>

QUESTION 40
kiruha [24]

Answer:

The correct answer is motion.

Explanation:

Lipids are the important constituents of plasma membrane. For example phospholipid,glycolipid,splingolipid,cholesterol builds most of the structural framework of the cell membrane.

Lipids plays an important role during cell signaling For example the phosphotidy inositol 4,5 bisphosphate one of important component of  the inner leaflet of the the plasma membrane undergo hydrolysis to form Diacylglycerol(DAG) and inositol triphosphate(IP3).Both IP3 and DAG act as second messenger.

Lipid act as an insulator of myelein sheath that helps in the saltatory conduction of nerve impulse across the axon of unmyelinated nerve fibre.

 Lipid does not involve in motion

Provide an example of how cells balance the redox potential between different cellular components?
crimeas [40]

En la respiración celular, la célula depende totalmente de las reacciones Redox, para ser precisos de la reducción del NAD a NADH y la oxidación de NADH a NAD.

Ahora veamos una situación diferente.

En la fotosíntesis, ocurre la reacción inversa de redox, como se muestra en la siguiente ecuación:

6CO2 + 6H2O + E --> C6H12O6 + 6O2

La energía biológica se almacena y se lanza con la frecuencia por medio de reacciones redox. La fotosíntesis implica la reducción del CO2 en azucares y la oxidación del H2O en oxigeno molecular (O2), mientras que en la respiración es lo inverso, la oxidación de azucares a CO2 y H2O.

Entre los pasos redox de la fotosíntesis, compuestos deducidos del CO2 reducen el NAD lo que crea entonces, la creación gradiente de protones, que conduce a la síntesis del ATP y es mantenida por la oxidación del O2.

En los seres vivos, el término redox se utiliza para describir el equilibrio NAD-NADH y NADP-NADPH.

El estado redox contribuye al equilibrio de los sistemas metabólicos. En el caso de alteraciones en las reacciones redox, puede producirse HIPOXIA, que es el déficit del O2 en la sangre, CHOQUE, que es el mal circulamiento de lal sangre y la SEPSIS.
