A psychology class uses a role-play to model a synapse. One group acts as the sending neuron and releases counters representing serotonin into the gap. Another group acts as the receiving neuron and holds receptor cards. Unused counters are either collected by the sending group to represent reuptake or removed to represent breakdown by enzymes. The class then introduces a card labelled SSRI.
Which change to the role-play correctly shows the action of the SSRI?
The sending group collects fewer serotonin counters, leaving more available to reach the receptor cards.
The SSRI card covers the receptor cards, reducing how many serotonin counters can reach them.
More serotonin counters are removed to represent enzyme breakdown, leaving fewer beside the receptor cards.
The sending group releases extra serotonin counters, so more of them reach the receptor cards.
