How does the cocaine molecule interfere with neurotransmitter uptake?

A) It has the correct size and shape to wedge itself into the neurotransmitter uptake channel.
B) It has the correct polarity to wedge itself into the neurotransmitter uptake channel.
C) It has the correct size, shape, and polarity to wedge itself into the neurotransmitter uptake channel.
D) None of the above

Neurotransmitter Uptake

The process by which neurotransmitters are reabsorbed by a neuron after the completion of a neural signal transfer.

Cocaine Molecule

The cocaine molecule is an organic compound with a complex structure that acts as a powerful stimulant in humans.

Polarity

A property of molecules showing the distribution of electrical charge, leading to molecules having a positive end and a negative end.

Final Answer :
C
Explanation :
Cocaine interferes with neurotransmitter uptake by having the correct size, shape, and polarity to wedge itself into the neurotransmitter uptake channel, effectively blocking the reuptake of neurotransmitters like dopamine, norepinephrine, and serotonin. This action increases the amount of these neurotransmitters in the synaptic cleft, leading to heightened stimulation of the post-synaptic neuron.
