Enzymes are known as catalysts in a chemical reaction, as they can reduce the time it takes for the reaction to occur by breaking things down. Enzymes are important to living things, because they can be found throughout the body to aid in things like digestion and fighting illnesses. A good example would be putting a Ritz cracker in your mouth and letting it dissolve. This happens because your mouth is full of enzymes that help break food down before entering the digestive system. Hope this helps! :)
Dopamine
On a biochemical level, cocaine blocks the reabsorption of the neurotransmitter dopamine.
Dopamine is a neurotransmitter (chemical) released by nerve cells in the body to transmit information from one neuron to another. Dopamine performs various important roles in the brain and body. Cocaine, which is a drug of abuse, blocks the reabsorption of dopamine. Cocaine acts by binding to the dopamine transporter, and stops the removal of dopamine from the synapse. Dopamine then increase in the synapse to form an amplified signal to the receiving nerve cells. This result in euphoria (feeling of intense excitement) experienced immediately after administering the drug.
