Conduction in gases and liquid depends on the movement of?
Ions
Electric current is constituted by the movement of?
answ2. Electrons. ions.
What transport mechanism is used to prevent to movement of sodium ions into the cell when it is at resting potential?
Passive transport - i.e., "leaky conductance" provided by NLCN channels for example.
What moves in a current?
Heat Energy
How do electrical currents pass through?
The prevailing theory is that the atoms in the conductor share electrons, and they seem to move around at random in the conductor material. When a voltage is applied across the conductor, the electrons tend to move in that direction, but they are still pretty random. This average trend is what we measure as current.
What is the movement of ions towards ions with an opposing charge?
oppositely charged ions attact each other.
What movement do ion channels aid?
the movement of ions across a cell membrane.
What molecules cause polarization and depolarization?
Sodium ions cause depolarization and potassium ions cause repolarization.
What's the direction sodium ions are pumped?
Sodium ions and potassium ions are pumped in opposite directions. Sodium ions are pumped out of the cell and potassium ions are pumped into the cell.
What is the substance that conducts electricity by movement of ions?
graphite
Conduction in gases and liquid depends on the movement of?
Ions
When copper sulfate ions are placed in water what type of movement of the ions will result in uniform distribution?
wieners are the best
The proton pump involves the movement of what?
Hydrogen ions (H+).
What is chemiosmis?
Chemiosmis is the movement of ions across a semipermeable membrane.
What counteracts the movement of bicarbonate ions from the RBC?
chloride shift
Electric current is constituted by the movement of?
answ2. Electrons. ions.
What the definition of current electricity?
the movement of electrically charged particles, atoms, or ions, through solids, liquids, gases, or free space; the term is usually used of relatively smooth movements of electric charge through conductors, whether constant or variable. Sudden movements of charge are usually referred to by other terms, such as spark or lightning or discharge. In metallic conductors the electric current is usually due to movement of electrons through the metal. The current is measured as the rate of movement of charge per unit time, and is counted in units of amperes. As a formal definition, the direction of movement of electric current is considered as the same as the direction of movement of positive charge, or in a direction opposite to the movement of negative charge. Electric current may move constantly in a single direction, called direct current (abbreviated DC), or may move alternately in one direction and then the opposite direction, called alternating current (abbreviated AC).
