In what way may drugs be used to affect neurotransmitters?
Orlov [11]
Drugs interfere with the way neurons send, receive, and process signals via neurotransmitters. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter in the body. This allows the drugs to attach onto and activate the neurons. Although these drugs mimic the brain’s own chemicals, they don’t activate neurons in the same way as a natural neurotransmitter, and they lead to abnormal messages being sent through the network.

Other drugs, such as amphetamine or cocaine, can cause the neurons to release abnormally large amounts of natural neurotransmitters or prevent the normal recycling of these brain chemicals by interfering with transporters. This too amplifies or disrupts the normal communication between neurons.

In the addition of hbr to 1-butyne the electrophile in the first step of the mechanism is
irga5000 [103]
Answer:
            <span>In the addition of hbr to 1-butyne the electrophile in the first step of the mechanism is <u>Hydrogen atom of HBr</u>.

Explanation:
                   In this reaction first of all HBr approaches the triple bond. A Pi Complex (weak inter-molecular interactions) is formed between the two molecules. And the triple bond attacks the partial positive hydrogen atom creating a negative charge on Bromine along with positive charge on itself (Sigma Complex). In second step the negative Bromide attacks the positive carbon of Butyne.</span>

The general formula for the alkyne series is:<br> CnH2n+2<br> CnH2n<br> CnH2n-2<br> CnHn+2
jeyben [28]
The general  formula  for  alkyne  series  is     CnH2n-2

 This is because alkyne  is unsaturated  hydrocarbon   which has  one  triple  bond   and   has  no functional  group  from   homologous series. Alkyne  has  a  general formula of  CnH2n-2

An  example  of an  alkyne  in  ethyne    with HC≡CH  chemical formula ,

another example is propyne   with  CH3C≡CH  formula
