CUET PG 2026 Agri-Business Management Question Paper (25-Mar-2026) (Shift 2)
The correct answer is
G- protein coupled receptor
Rhodopsin Receptor Type Identification
Rhodopsin is a light-sensitive pigment found in the photoreceptor cells (rods) of the retina. Its primary role is in vision, detecting photons of light.
The question specifies that rhodopsin does not respond to neurotransmitter molecules. This characteristic helps distinguish its receptor class.
Rhodopsin belongs to the superfamily of G-protein coupled receptors (GPCRs). GPCRs are integral membrane proteins that detect molecules outside the cell and activate internal signal transduction pathways.
- While many GPCRs bind neurotransmitters, rhodopsin specifically binds to photons (light).
- Its activation triggers a signaling cascade involving the G-protein transducin, leading to a cellular response (vision).
- The prefixes C-, M-, and n- in the options do not represent standard classifications for this type of receptor.
Therefore, rhodopsin is classified as a G-protein coupled receptor.
