Dopamine is a neurotransmitter involved in the reward pathways in the brain, and its decreased activity has been associated with
diseases such as Parkinson’s disease and attention-deficit/hyperactivity disorder (ADHD). Which of the following drugs is NOT a likely candidate to treat these diseases? A. Methylphenidate, a dopamine reuptake inhibitor
B. Amphetamine, a dopamine-releasing agent that triggers the release of dopamine into the synaptic cleft
C. Carbidopa, which enhances the availability of the dopamine synthesis precursors in the brain
D. Forskolin, a sensitizer of dopamine receptors
E. Chlorpromazine, a dopamine antagonist that binds to and inhibits dopamine receptors
The answer is E; Chlorpromazine, a dopamine antagonist that binds to and inhibits dopamine receptors
Explanation:
Chlorpromazine which is a dopamine antagonist is not a candidate to treat Parkinson's disease and attention-deficit/hyperactivity disorder (ADHD) because as a dopamine antagonist it works by binding to dopamine receptors but does not activate it, thus blocking the actions of dopamine or exogenous agonists.
Muscles need much more energy. Mitochondria are the powerhouse of the cell and produces all of the ATP that a cell needs. The more mitochondria there is, the more energy that is produced
The answer in this question is known as antisepsis. Antisepsis is the chemical agents that is used directly on exposed body surfaces to destroy or inhibit vegetative pathogens. Antisepsis is defined as the practice of using antiseptic to eliminate the micro-organism who causes of having a disease.
