Answer:
Explanation:
La tercera ley de Newton o principio de acción y reacción establece que cuando dos cuerpos interacción aparecen fuerzas iguales y de sentidos opuestos en cada uno de ellos.
Answer:
4) Replacement of GDP by GTP on the Ga after interaction with an activated GPCR.
5) Conformational change in the Ga subunit causing a decreased affinity for the Gb g subunit.
2) Dissociation of Ga from the G protein complex.
6) Ga-subunit with its attached GTP activates an effector like adenylyl cyclase.
3) Production of a second messenger, like cAMP.
1) Activation of one or more cellular signaling proteins.
Explanation:
It is a signaling cascade initiated by G proteins. These G proteins function as molecular switches capable of activating signaling pathways in the presence of guanosine triphosphate (GTP), which is hydrolyzed in order to produce energy
<span>In biological terms, the structure of a species is usually best adapted to give it the most advantageous functional ability, though this is not always the case. When a structure has a function that allows the species to survive and promulgate its genetic structure, the individual will be more likely to reproduce its genotype over those that are not structurally advantageous.</span>
