Rods and cones are similar in that they both _____. see concept 50.3 (page 1117) view available hint(s) rods and cones are similar in that they both _____. see concept 50.3 (page 1117) respond to all wavelengths of light depolarize when exposed to light fire action potentials when exposed to light use photopsins as the visual pigments in both rods and cones release glutamate as the primary neurotransmitter

Answer 1

Rods and cones are similar in that they both release glutamate as the primary neurotransmitter. During signalling the rod and cone photoreceptors signal their absorption of photons via a decrease in the release of the neurotransmitter glutamate to bipolar cells at its axon terminal. Every rod and cone photoreceptor release the same neurotransmitter, glutamate.
