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.

3. What are some scientific explanations for the history of life on Earth?
KATRIN_1 [288]

Answer:

Many scientists favor the RNA world hypothesis, in which RNA, not DNA, was the first genetic molecule of life on Earth. Other ideas include the pre-RNA world hypothesis and the metabolism-first hypothesis. Organic compounds could have been delivered to early Earth by meteorites and other celestial objects

A geneticist introduces a transgene into yeast cells and isolates five independent cell lines in which the transgene has integra
Zina [86]

Answer:

A) A transgene integrated into a heterochromatic region of the genome.

Explanation:

This is most likely the reason why the transgene is not expressed in the fifth cell line. It is likely that the transgene was integrated into a heterochromatic region of the genome. Heterochromatin consists of genetically inactive satellite sequences, and many of these are repressed to various extents. Moreover, because this is a tightly packed form of DNA or condensed DNA, it is inaccesible to polymerases and thus not transcribed.

in 6-8 sentences, explain how stream volume and speed affect the size, shape and flow of streams and rivers.
sukhopar [10]

Explanation:

The higher the volume of water in a stream, the higher its speed and the wide its size and shape which ensures a proportionate flow rate.

To quantify how the speed of stream, we use the quantity, discharge in hydrology;

 Discharge is the volumetric rate of water flow past a point at a particular time.

  Discharge = \frac{volume of water}{time}

  • We see that discharge is directly proportional to the volume of water in a stream.
  • It is inversely proportional to the time taken.
  • We know that volume is the amount of space occupied by a body. It is function of its size and shape.
  • A big water body that is deeper, wider and longer will have more wate and a greater discharge.
