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.
Is the inside of the cell more positively charged than the outside.?
No, the inside of a cell is typically more negatively charged compared to the outside. This difference in charge is primarily due to the distribution of ions, particularly sodium (Na⁺) and potassium (K⁺), as well as negatively charged proteins and other molecules inside the cell. The resting membrane potential of a cell usually ranges around -70 mV, indicating that the interior is negatively charged relative to the exterior.
What is the charge on the inside membrane during the resting membrane potential?
The inside membrane is negatively charged during the resting membrane potential, typically around -70mV. This is due to the uneven distribution of ions across the cell membrane, with more negatively charged ions inside the cell compared to outside.
What is an atom's subatomic parts?
Positively charged protons and neutral neutrons (inside the nucleus) and negatively charged electrons revolving outside the nucleus.
What are the relative charges on eiter side of the membrane?
The inside of the cell is negatively charged compared to the outside due to an abundance of negative ions such as proteins and nucleic acids inside the cell. This creates an electrical potential across the membrane known as the membrane potential.

When the inside of a cell is negatively charged while the outside of the cell is positively charged it is known as resting potential true or false?
True. This difference in charge, with the inside of the cell more negatively charged compared to the outside, is known as the resting membrane potential. This is a key characteristic of the resting state of a neuron.
Why is the inside of the cell membrane negatively charged at resting potential?
The inside of the cell membrane is negatively charged at resting potential because of an unequal distribution of ions, specifically more negatively charged ions inside the cell compared to outside. This creates an electrical potential difference across the membrane, known as the resting membrane potential.

No, the inside of a cell is typically more negatively charged compared to the outside.

When the outside of a nerve is positively charged and the inside is negatively charged what is this called?
action potential
What is the charge on the inside membrane during the resting membrane potential?
The inside membrane is negatively charged during the resting membrane potential, typically around -70mV. This is due to the uneven distribution of ions across the cell membrane, with more negatively charged ions inside the cell compared to outside.

A polarized neuron has fewer positive ions inside in comparison to the outside of the neuron?
A polarized neuron has a more negative charge inside compared to the outside due to the presence of more negatively charged ions inside the neuron. This difference in charge is maintained by the activity of ion pumps and channels in the neuron's cell membrane.
The inside of a typical cell?
negatively charged
Why is the resting membrane potential negatively charged?
The resting membrane potential is negatively charged because of the unequal distribution of ions across the cell membrane, with more negative ions inside the cell than outside. This creates an electrical gradient that results in a negative charge inside the cell at rest.
What type of electric charge does a electron have?
They are negatively charged particles. electrons are found inside an atom, outside its nucleus.
