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.

Where are the ovules stored?

Alina [70]

The style is the long tube that attaches the stigma to the ovary. Sperm from the pollen will travel down this tube to the ovules. The ovules, or eggs, are stored in the ovary until they are fertilized. Plants can only fertilize eggs of the same species.

our study partner has drawn four models of membrane-bound vesicles to try to show what a vesicle would look like with water both

Citrus2011 [14]

Answer:

The answer (Image 1) is attached. Since the options weren't provided, I've attached the image of the options, too.

Explanation:

The plasma membrane is composed of phospholipids, a special form of lipids with a hydrophilic head and hydrophobic tail. According to the fluid mosaic model, the hydrophilic heads are positioned towards the outside where they freely interact with the extracellular matrix and cytosol. Whereas, the hydrophobic tails are positioned towards the inside so they aren't exposed to water.

Liposomes are lipid bases particles used for drug and vector delivery. The picture shows a typical liposome.

In the current case, for water to move both outside and inside, hydrophilic heads should be present inside as well as outside the tails.

The light reaction of photosynthesis puts carbon dioxide into the form of carbonhydrates

Dima020 [189]

Answer:

hey! hope this helps love!

Dark reaction means that light is not necessary for this part of photosynthesis. In the dark reaction, CO2 from the atmosphere is fixed or becomes part of a carbohydrate dioxide into the form of carbohydrates-organic molecules used as food for the plant. This process is called the Calvin Cycle.

What is the major cause of the greenhouse effect? view available hint(s) what is the major cause of the greenhouse effect? exces

Strike441 [17]

The major causes of the greenhouse effect is excessive carbon dioxide gas in the atmosphere. The greenhouse effect is a process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by green house gases, such as carbon dioxide, water vapor, metahne, nitrous oxide, and ozone. The absorbed energy warms the atmosphere and the surface of the Earth.
