Answer:
Mayra should be checked regularly for heart-related problems.
Because the chain will begin to shut down and will no longer pump [H+] (hydrogen ions) across the membrane; thus, the proton gradient can not be maintained.
:) I hope this answers your question!
When a signal molecule binds a membrane receptor, different intracellular events occur in response. Option D is correct: All of the above.
<h3>
What is signals translation and how is it done?</h3>
Signal translation is the conversion global process of extracellular signals into intracellular responses. This porcess is done by a translator.
Translation might be
- INDIRECT ⇒ <u>Second messengers</u> participate in the signal translation, mediating between receptor and the cellular response.
The receptor-ligand union causes the production of second messengers that will activate effector proteins. Occurs an amplification of the signal.
- DIRECT ⇒ Occurs directly in the membrane.
<u>Ionic channel proteins</u> are activated and can change the chemical signal into an electric signal through ion flow.
When the molecule binds receptors that are associated with enzymes -or acting as enzymes- or to G proteins, it occurs a conformational change in the receptor cytoplasmic domain.
This change triggers an intracellular signal cascade in which many molecules participate and several<u> chemical changes</u> occur.
According to this framework, all the options are correct,
- The receptor can open an ion channel in the cell membrane.
- The receptor can act as an enzyme causing chemical changes in the cytoplasm.
- The receptor can cause the formation of a second messenger.
So te correct option is Option D. All of the above.
