Answer:

the proteins on its surface and that of the host

Explanation:

The process of viral infection begins with the entry of the virus to its host cells. For this purpose, viral surface proteins attach to receptor proteins found on target host cells. For example, the coronavirus responsible for the pandemic contains spike (S) proteins on its surface that bind to angiotensin-converting enzyme 2 (ACE2) receptors and thus infects host target cells. Moreover, the specificity of the binding determines the ability to infect and the host range of the viruses. In the case of coronavirus, it has been suggested that ACE2 receptors are not fully developed in children, thereby children would be less susceptible to viral infection.

Which hormone does the sympathetic nervous system release to increase heart rate.
sertanlavr [38]

The sympathetic nervous system releases hormones known as catecholamines which increase the heart rate.

<h3>What is a heart rate? </h3>

it is the number of contractions of the heart per minute.

<h3>What are catecholamines?</h3>

These are the neurotransmitters that have a catechol and a side chain that is an amine.

<h3>Which catecholamines are released by the sympathetic nervous system?</h3>

Epinephrine and norepinephrine are the catecholamines that are released by the sympathetic nervous system to increase the heart rate.

<h3>Where are these hormones released?</h3>

These hormones are released in the blood.

<h3>How does this hormone increase the heart rate?</h3>
  • "These hormones are released at the neuromuscular junction of the cardiac nerves."
  • "They shorten the repolarization period."
  • This speeds up the rate of depolarization and contraction and thus the heart rate is increased.
