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.

Reduction in cGMP causes:

Go with B — Closing of Na⁺ channels. Within Sensory System Eye Physiology, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, excitable-cell physiology turns on membranes, ions, and signalling steps, and Closing of Na⁺ channels captures the correct piece of that story. Holding that picture in mind makes Closing of Na⁺ channels 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 Closing of Na⁺ channels.

Activated transducin stimulates which enzyme?

Pick C: cGMP phosphodiesterase. 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: cGMP phosphodiesterase is the option that correctly names the structure, process, or principle asked for in Sensory System Eye Physiology. Hence cGMP phosphodiesterase is correct. Treat this as a building block for the rest of Sensory System Eye Physiology; neighbouring topics often reuse the same principle.

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.
