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.

Explanation:
The Consent Form is the document that explains, in clear and objective language, all the procedures, advantages and disadvantages of being a research subject in a given protocol. It is the first step for the patient to join a study. This term must be signed by anyone who will participate in a scientific research. It should not contain the basic information of the sponsor and the Ethics Committee that approved this project, and is mandatory for all participants. Dr. Portree wants to do a study with students from a university without allowing them to sign the consent form, this is very serious because it violates ethical research rules, so it should be prevented from conducting your study.
The best way would be to explain to them that she does not drink. If they do not respect her decision, then simply that is not the group of people she should be around.
