Answer:
The ability of caffeine to inhibit adenosine receptors, plays a very important role in heightened alertness and sleeplessness.
Explanation:
"<em><u>Caffeine</u></em>" (<em>1,3,7-trimethylxanthine</em>) is an alkaloid obtained from plants. It has a chemical formula of C8H10N4O2.
Caffeine is generally <em>hydrophillic</em> but sufficiently <em>lipophilic</em> to pass through all biological membranes and readily cross the blood-brain barrier.
Therefore can bind with the adenosine receptors. Due to the blocking of adenosine inhibitory effects through its receptors held by paraxanthine and caffeine, it indirectly affects the release of <u>norepinephrine, dopamine, acetylcholine, serotonin, glutamate</u> e.t.c.
The release of the above-mentioned hormones have a great impact on the heightened alertness of the body, especially <em>dopamine</em> and <em>serotonin</em>.
It is the Watt per square meter, or W/m2.

A list of the cell fibers from largest to smallest would read:
1. microtubules – is a microscopic tubular structure that is present in numbers in the cytoplasm of cells. These are usually aggregated to form complex structures.
<span>2. intermediate filaments – are cytoskeletal components that is usually found in the cells of vertebrate species and </span>other organisms like plants, fungi, unicellular organisms.
3. <span>Microfilaments – are filamentous structures that can be found in the cytoplasm of eukaryotic cells and it will form part of the </span>cytoskeletons<span>. They are composed primarily of polymers of actin. But in cells, they usually interact with other proteins.</span>
