Decide if these retinal events occur in the dark or in the light. Rods continuously release the neurotransmitter glutamate. Glutamate inhibits the bipolar cells that synapse with the rods. The bipolar cells do not stimulate the ganglion cells. Activated rhodopsin inhibits the production of glutamate by rods. The bipolar cells stimulate the ganglion cells. Action potentials are transmuted out of the optic nerve.

Solution

Answer:

1. Rods continuously release the neurotransmitter glutamate---Dark.

2. Glutamate inhibits bipolar cells synapsing with the rods—Dark.

3. The bipolar cells do not stimulate ganglion cells-Dark

4. Activated rhodopsin inhibit the production of glutamate by rods—Light

5. The bipolar cell stimulate the ganglion cells—Light

6. Action potentials are transmitted out of the optic nerve--Light
