Exercise plays a part in affecting the release of hormones. How would you expect exercise to affect growth hormone and hormones
Rudik [331]

Answer:

Exercise plays a significant role in affecting hormonal discharge inside a human body.

Explanation:

Hormones are the chemical substances that are a part of the body's signaling systems. <em>Deem them as little traffic cops!</em> They regulate things like growth, metabolism, and reproduction in human bodies.

<h3>Human Growth Hormone</h3>

<u>What is it:</u> Anabolic peptide hormone that incites cellular growth, secreted by the anterior pituitary gland.

<u>Its job:</u> Increases muscle protein synthesis for the growth of muscles, increases mineralization of the bones, supports the immune system, and promotes lipolysis.

<u>How exercise affects it:</u> Our bodies produce it periodically on its own. However, some exercises, such as high-intensity workouts that involve heavy strength training and cardio-respiratory exercise, stimulate and increase its production at the onset of blood lactate.

<h3>Epinephrine and Norepinephrine (Adrenal Medulla Hormones):</h3>

<u>What is it:</u> Amine hormones help in the sympathetic nervous system produced by the adrenal gland.

<u>Its job:</u> Facilitates sympathetic (fight or flight) activity, increases heart activity, increases glycogen catabolism, and fat release.

<u>How exercise affects it:</u> Their stimulation increases during cardiovascular exercise to promote the breakdown of glycogen to provide energy to muscles.

d1i1m1o1n [39]

Answer:

3.14 residues

Explanation:

This kind of sheets has the particularity that the distance between adjacent residues is 3.5 Angstroms. Furthermore, there are two residues per cycle.

Hence, we can calculate easily the number of residues in a segment, by using the expression:

Nr = (256 Å) / (3.5 Å/residue) = 3.14 residues

I hope this is useful for you
