1. Why are essential proteins so important to a
healthy diet?<span>
Proteins are a “macronutrient” (just like carbohydrates and fat), which means
that your body needs a large amount of them in order to stay healthy. A healthy
diet requires a balance between the macronutrients and the “micronutrients”
(such as vitamins and minerals, which the body needs in smaller amounts). </span>

2. How does the body use protein?<span>
The body uses proteins to: create and repair tissues; build enzymes, chemicals,
and hormones; every cell in your body is in fact made up of proteins; and it is
also the building block of bones, muscles, cartilage, skin, and blood.</span>

<span>4. Name and describe a category of
vegetarianism.
</span><span>A branch of
vegetarianism is Veganism. A vegan does not eat any products that derive from
animals, for example: milk, cheese, butter, eggs, etc. as a step forward to
vegetarianism which simply cuts meat and fish out of the diet. Vegans though
need to replace those nutrients from products that are organic a non-animal-derivate
such as soy, for example. </span>
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.
