If a ligand were stuck in the g-protein-linked receptor, what would be the effect to the cell?.
aleksandr82 [10.1K]

The pathway would be over active, If a ligand were stuck in the G-protein-linked receptor.

<h3>What usually happens when a ligand binds to a receptor protein?</h3>

When the ligand attached to the internal receptor, a change occurs that shows at DNA-binding site on the protein.

The ligand-receptor complex moves into the nucleus where it binds itself to regions of the chromosomal DNA. It promotes the initiation of the process of transcription so we can conclude that if a ligand were stuck in the G-protein-linked receptor, the pathway would be over active.

beks73 [17]

Answer:

Natural selection

Explanation:

According to  Darwin's theory, natural selection is the process by which individuals better adapted to their environments have more chances to survive and reproduce, and thereby their descendants will be better represented in the next generation. This mechanism exploits the existence of natural variation among members in the population which is used to select those individuals that are better adapted (i.e., with a higher adaptive fitness) for their environments. Natural selection is a key mechanism of evolution by which species change across time.
