The Effects of Too Much Carbon Dioxide in the Blood. Excess CO2 can affect you just like a physical obstruction to breathing. Photo Credit Jupiterimages/Goodshoot/Getty Images. Carbon dioxide (CO2) is a gas that's always present in your blood. It is the waste product generated as your body uses up oxygen, and it is expelled from the lungs when you exhale.
Many neuropsychological conditions such as anxiety and depression are directly related to the imbalance of neurotransmitters. Common neurotransmitters include acetylcholine, dopamine, norepinephrine and serotonin etc.
Binding of acetylcholine to a muscarinic AChR causes a conformational change in the receptor that is responsible for its association with and activation of an intracellular G protein, the latter converting GTP to GDP in order to become activated and dissociate from the receptor.he muscarinic AChRs occur primarily in the CNS, and are part of a large family of G-protein-coupled receptors (G proteins), which use an intracellular secondary messenger system involving an increase of intracellular calcium to transmit signals inside cells.
