General Biology - Part 2

A patch clamp device is used to

The principle of core biological organization explains that structure-function relationships govern cellular processes. Hence study the properties of individual membrane channels fits best because it integrates fundamental principles, as documented in authoritative sources on general biology.

Ref: Campbell et al., Biology, 11th Edition, Chapter 2, Chemical Basis of Life, discusses fundamental biological principles and molecular organization providing broad foundation for life sciences understanding.

A patch–clamp device is used to

This outcome reflects core biological organization, where structure-function relationships govern cellular processes. Option D captures this correctly because it integrates fundamental principles, consistent with textbook descriptions and experimental observations in general biology.

Electrophysiological methods

Which technique allows the study of electrical activity of single ion channels?

Patch-clamp achieves electrical isolation of a tiny membrane patch by forming a gigaohm seal between a fire-polished glass micropipette and cell surface, enabling resolution of picoampere currents through one ion channel. Developed by Erwin Neher and Bert Sakmann, configurations include cell-attached, inside-out, outside-out and whole-cell, allowing study of voltage-gated, ligand-gated and mechanosensitive channels, single-channel conductance, open probability and kinetics. Single-unit recording monitors whole neuron firing, EEG sums thousands of cortical postsynaptic potentials, MRI uses prot
