Depressants often cause slow movements and loss of sense of balance. These chemical substances reduce the speed and ability of neurotransmitters to communicate. Included in this category of substances are opioids, alcohol and marijuana related products. Pharmacological-related substances are sleeping pills and pain relievers, to help aid sleep and relax muscles.
Protein is considered as a Neurotoxin.
What do you mean by Neurotoxin ?
- Neurotoxins can be considered as toxins that are destructive to nerve tissue.
- They are an extensive class of exogenous chemical neurological insults that can adversely affect function in both developing and mature nervous tissue
- The active botulinum toxin occurs naturally as part of a high molecular weight complex containing the neurotoxin moiety and a set of complexing proteins of clostridial origin.
- The proteins are also called neurotoxin-associated proteins.
Hence, in the above case it can be concluded that Protein is a neurotoxin.

Answer: It helps to regulate circadian rhythm
Exposure to natural light during the day helps regulate the circadian
rhythm, which improves sleep pattern. The term circadian rhythm refers to our
biochemical, physiological and behavioral processes in approximately 1 full day
cycle. Circadian rhythm plays an
important role in
controlling when we fall asleep and when we wake up.
During day light, the secretion of melatonin or sleep hormone is
suppress by melanopsin that keeps people awake and alert. Nevertheless, during nighttime,
melanopsin stimulates the release of melatonin to signal sleeping time. Therefore,
this hormone works the entire day and has direct effect on the circadian
rhythm, which acts as a regulator of our biological clock.
