Caffeine: A Central Nervous System
Caffeine is a central nervous system stimulant of the methylxanthine class. It is one of the most worldwide consumed psychoactive substances and it is totally legal. The chemical name of caffeine is 1, 3, 7 – Trimethylpurine – 2, 6, - dione. Its molecular formula is C8H10N4O2 and it has a molecular mass of 194.19 g/mole. Caffeine is an odourless, white crystalline purine, a methylxanthine alkaloid, which is closely chemically related to adenine and guanine.
Caffeine acts through multiple mechanisms, however the most prominent of which is the antagonism of adenosine receptors (ADORA1 and ADORA2) and consequently it prevents the onset of drowsiness induced by adenosine.
Normally adenosine accumulates as time pass in the neuronal synapse.

    Effect of Caffeine on Heart Rate in Daphnia

    Caffeine belongs to a class of compounds called methylxanthines and can block a receptor on the surface of heart muscle cells for adenosine. In fact, it is caffeine's blockade of the A1 adenosine receptor in the heart that causes the heart to pound after a significant caffeine dose. Caffeine and similar compounds also inhibit a class of enzymes known as cyclic nucleotide phosphodiesterases. These enzymes are, in part responsible for degrading a stimulatory signal produced when excitatory neurotransmitters activate different neurons in the central nervous system (CNS). Thus, when they are inhibited by caffeine, the stimulatory signal remains active for a longer period of time resulting in a greater sense of alertness (a CNS effect) but also a higher heart rate, blood pressure and respiratory rate. Caffeine also acts as a stimulant drug, causing increased amounts of stimulatory neurotransmitters to be released. At high levels of consumption caffeine has been linked to restlessness, insomnia and anxiety, causing raised stress and blood pressure. This can lead to heart and circulation problems.…

    Caffeine In The Brain

    Caffeine is a drug commonly used as a central nervous system stimulant. It is found in plants like coffee and tea. Caffeine can also be found in soft drinks, and it is regarded as the most widely consumed stimulant drug in the world based on Nehlig, Daval, & Debry (1992) research. The interaction of caffeine with adenosine receptors in the brains makes an individual more alert. A moderate intake of caffeine results in small healthy risks while high doses could be a catalyst to negative effects like anxiety, insomnia, and tachycardia. Research has shown that caffeine is widely abused. Clinical data available suggest that withdrawal should be considered as a diagnostic manual in the United States (Reissig et al., 2009). The role adenosine contributes…
