What best describes the Na and K concentrations across a neuron's plasma membrane?
The Na concentration is higher outside of the neuron's plasma membrane, while the K concentration is higher inside the neuron's plasma membrane. This creates an electrochemical gradient that allows for the generation and transmission of electrical signals in neurons.
What best describes the Na plus and K plus concentrations across a neuron's plasma membrane?
None of the following do.
A polarized neuron has fewer positive ions inside in comparison to the outside of the neuron?
True
What is restpotential?
The resting membrane potential of a neuron is about -70 mV (mV=millivolt) - this means that the inside of the neuron is 70 mV less than the outside. At rest, there are relatively more sodium ions outside the neuron and more potassium ions inside that neuron.
Which condition is a neuron in when the outside of the neuron has a net positive charge and the inside has a negative charge?
resting potiental
When a neuron is resting the inside of the cell membrane is?
When a neuron is resting then inside of the cell membrane is more negative than outside.
What do resting and action potentials depend on?
The resting and action potentials depend on the balance of charges of the area outside the neuron and inside the neuron. A resting potential is when the neuron is more negatively (approximately -70mv) charged than the area outside the neuron. The action potential occurs when sodium ions rush into the neuron, causing the polarity to be reversed. When there is no difference in charge between the area inside the neuron and the area outside the neuron, no action potentials can be started by that neuron.
The charged particles located inside and outside of the neuron are called?
ions
If the inside of the neuron is negatively charged compared to the outside the neuron is in the?
If it's approximately -70 mV, then it's in a resting state.
It is the membrane potential of a neuron at rest?
Yes,the membrane potential of a neuron is at rest because it is the difference in electrical charge between inside and outside a resting neuron.
What is the concentration of sodium in a neuron?
its about 10mM inside and 140 mM outside the cell.
How does the inside of the resting neuron compare to the outside in terms of electrical charge and Na plus concentration?
The concentration of negatively charged proteins and positively charged potassium ions, K+, is greater inside the cell than outside. In contrast, the concentration of sodium ions, Na+, is greater outside the cell than inside. The concentrations of Na+ and K+ ions are partly due to the action of the sodium-potassium pump, which actively moves Na+ out of cells while moving K+ in.
