To which ion is the resting cell membrane most permeable? Na+ or K+? Therefore, ___ is the major ion contributing to resting membrane potential. Fill in the blank: Membrane potential is measured in. Fill in the blank: Depolarization is a _ in resti...
Fill in the blank: Membrane potential is measured in. Fill in the blank: is the organelle responsible for processing and packaging proteins and lipids made by the cell. The cell membrane functions to: A. Maintain wholeness of the cell. B. Control the entry and exit of various...
The potential difference’s magnitude, in between, is measured in millivolts (mV) or volts (V). This voltage is measured with a voltmeter. The sign of a membrane’s voltage indicates the charge present on the inner surface of a polarized membrane. A negative value, such as −60 mV, ...
Passing a Current Across the Membrane Changes the Membrane Potential Figure 3.2.3 shows a highly schematic diagram of how the membrane potential can be measured by inserting a microelectrode through the membrane of the axon. The resting membrane potential in these axons is about −60 mV. Rec...

Changes of membrane-potential-related fluorescence intensity (MPRFI) in 69-V were measured by flow cytometry. For that purpose the cells were stained with the dye 3,3′ -dihexyloxacarbocyanine iodide (diOC(3)), which is bound to the inner side of the cytoplasmic membrane bilayer. The MPRFI...
For the investigation of the permeability of the yeast cell wall, the concentration changes of TPP+ions as a function of time was measured. A custom-build mini-potentiostat with a special high sensitivity electronic circuit, protected against static electrical interference, was used for the measureme...
The effects of increasing stimulation frequency (from 0.2 to 1.4 Hz) on the contractility, intracellular Ca(2+) concentration ([Ca(2+)](i)) and membrane potential of single ventricular myocytes isolated from the heart of rainbow trout (Oncorhynchus mykiss) were measured. Cell shortening, expresse...
Then the mitochondrial membrane potential was measured by using mitochondrial membrane potential assay kit with JC-1. 10 μg/ml of JC-1 working solution was added into the cultures for 30 min at 37 °C in the dark. After washing, the images were captured using an IX73 fluorescence ...
