16. During the signal transduction process, the signal often triggers a signal transduction cascade. For example, a single activ

ated receptor can activate hundreds of protein A molecules. Each activated protein A molecule activates hundreds of protein B molecules, and so on, until a cellular response occurs. What purpose does this cascade serve

Answer:

The cascade amplifies the signal.

Explanation:

The purpose of the cascade is to transmit a signal to other components in the shortest time possible and do it massively, so when a receptor is activated, this affects a high number of receptors. By doing a cascade reaction, the information travels very fast, achieving the objective quickly, and without a significant loss of energy, in other words, is an efficient method.

9. Which is the pathway of oxygen from lungs into the body tissues?
Setler [38]

Answer:

The pathway of oxygen from lungs to the body tissues is alveoli → red blood cells → blood vessels → tissues (option b).

Explanation:

The oxygen (O₂) required by the tissues comes from the air inspired by the respiratory system. The pathway of entry of O₂ to the body and tissues is:

  1. O₂ from the air reaches the lungs.
  2. In the pulmonary alveoli, gas exchange occurs, that is, O₂ passes into the blood capillaries and is captured by the red blood cells, while CO₂ is released and passes into the alveoli to be eliminated.
  3. O₂ in the red blood cells travels through the blood vessels.
  4. The tissues receive the O₂ and a second gaseous exchange occurs at the tissue level, as they release CO₂ that will be carried to the alveoli.

Tissue oxygenation depends on the integrity of the respiratory and circulatory systems.

<em>     The other options do not show the correct order in which the oxygen travels from the alveoli to the tissues.</em>

What is the priority nursing intervention in the postictal phase of a seizure?
tiny-mole [99]
<span>The answer is: assess the client's breathing pattern.

</span> In the postictal phase, the phase after the seizure, the brain recovers from the trauma caused by the seizure. In this phase the priority is to assess the patient's breathing pattern for effective rate, rhythm, and depth. For this is necessary to apply oxygen and ventilation.
