← Human Body & HealthIf a patient's retinal bipolar cells lose their ability to respond to glutamate released by photoreceptors, which consequence follows?
A)Increased rhodopsin production occurs
B)Light perception will be impaired✓
C)Dark adaptation sensitivity increases
D)Color vision becomes more acute
💡 Explanation
When bipolar cells cannot respond to glutamate, they are unable to relay signals from photoreceptors to ganglion cells, because this disruption prevents visual information from being transmitted. Therefore, light perception is impaired, rather than enhanced dark adaptation or color acuity, which depend on functional bipolar cell signaling.
