Tju [1.3M]

Answer:

Adenosine.

Explanation:

Adenosine is a neurotransmitter that is created in the brain and when it binds to the adenosine receptors, it slows down nerve activity and it creates a sensation of drowsiness.

<u>Caffeine</u> looks like adenosine to the receptors, therefore, when we have caffeine, <u>it binds to these receptors and there is no room left for the adenosine to bind</u>. However, the caffeine doesn't slow down nerve activity but, in the contrary, it speeds it up.

Therefore we can tell that caffeine blocks the receptors for the adenosine thus promoting wakefulness.

What is Muscular Strength and Body Composition?
MissTica

Answer:

Muscular Strength: Muscular strength refers to the amount of force a muscle can produce with a single maximal effort. The size of your muscle fibers and the ability of nerves to activate muscle fibers are related to muscle strength. It is measured during muscular contraction. Building muscle strength helps with body alignment, makes performing everyday actions easier, and increases metabolism.

Body composition: Body composition is a method of breaking down the body into its core components: fat, protein, minerals, and body water. It describes your weight more accurately and provides a better glimpse into your overall health than traditional methods. Body composition analysis can accurately show changes in fat mass, muscle mass, and body fat percentage.
