Sensory System Eye Physiology

In light, membrane potential of rod cell becomes approximately:

Pick C: -65 mV. Thinking about Sensory System Eye Physiology in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: -65 mV is the option that correctly names the structure, process, or principle asked for in Sensory System Eye Physiology. Hence -65 mV is correct. Treat this as a building block for the rest of Sensory System Eye Physiology; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions.

Ref: Animal physiology is Unit 7 of the CSIR NET Life Science Syllabus, covering core body systems. It accounts for roughly 10% of the total marks in Sections B and C.

Which enzyme converts cis-retinal to trans-retinal?

Go with C — Isomerization (photoisomerization). Within Sensory System Eye Physiology, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, Isomerization (photoisomerization) is the option that correctly names the structure, process, or principle asked for in Sensory System Eye Physiology. Holding that picture in mind makes Isomerization (photoisomerization) feel natural rather than something you only memorise. Link the term to a real body example (organ, tissue, or ion flow) so the idea stays concrete under exam pressure. A short mental diagram helps — start from stimulus or structure, follow the pathway, and stop at the functional result described by Isomerization (photoisomerization).

Dark current in photoreceptors is due to:

Pick B: Opening of Na⁺ channels. Thinking about Sensory System Eye Physiology in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: cause and effect line up with Opening of Na⁺ channels — that is the mechanism or reason the stem is pointing to. Hence Opening of Na⁺ channels is correct. Treat this as a building block for the rest of Sensory System Eye Physiology; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions.
