3. Nombra las reacciones que ocurren en el paso de<br> Alfacetoglutarato a succinato
Shkiper50 [21]

Answer:

Hidrólisis y oxidación.

Explicación:

La hidrólisis y la oxidación son las reacciones que ocurren en el paso del alfacetoglutarato a succinato. En el quinto paso hay una hidrólisis del grupo tioéster de CoA en la que los átomos de los compuestos se rompen y luego sustituyen sus elementos miembros. Esta reacción de hidrólisis libera energía y se hace un ATP a partir de ADP. En el paso 6, succinato a fumarato es una oxidación para poner en el doble enlace significa que FAD se reduce a FADH2. Entonces podemos decir que la hidrólisis y la oxidación son las reacciones que ocurren en el paso de Alfacetoglutarato a succinato.

a scientist finds an organism that has a single cell without a nucleus this organism was found in pond water in which kingdom do
Fantom [35]

Answer:

Protista

Explanation:

In biology, there are said to be six different kingdoms that an organism can be classified under. They include Animalia, Plantae, Fungi, Protista, Archaea/Archaebacteria, and Bacteria/Eubacteria.

With this in mind, you say that a unicellular (single-celled) organism without a nucleus was found in pond water. This would point to the Protista kingdom, which are also known as protists. These organisms are single-celled beings with no big nucleus that are typically found in environments like ponds.

Hope this helped! I will take my 100,000 dollars via wire transfer (or just give this answer branliest)
