The correct option is A It is obtained from the plant native to Africa
Neurotransmitters are chemical messengers that send signals from one neuron to another.
Dopamine is a neurotransmitter produced in the brain. Dopamine along with its receptors plays an important role in movement regulation and has a prominent effect on emotions.
During the transmission of impulse (signal) between two adjacent neurons, dopamine is released in the space or cleft between them. This space is called the synaptic cleft.
On the release of dopamine from one neuron, it binds to its specific receptors on the second neuron, successfully transmitting the signal between the two neurons. It has been observed that the individual when happy often shows increased levels of dopamine.
However, dopamine is collected by a protein called transporter, thus clearing it out from the synapse. Once dopamine is taken back by the transporter, the feel-good sensation settles down.
Cocaine is a psychoactive drug obtained from Erythroxylum coca, a plant native to South America. Cocaine is commonly called coke or crack.
Cocaine blocks the transporter and interferes with the uptake of dopamine from the synapse. This leads to continuous binding of dopamine to its receptors and thus amplifying the effect of dopamine. Thus, cocaine produces a sense of euphoria and increases the energy level and acts as a stimulant.
The excess dose of cocaine also causes hallucinations.
The perceptions in the absence of a stimulus and accompanied by a compelling sense of reality are called hallucinations.
