What is the relationship between membrane potential and resting potential in a cell?
The resting potential of a cell is the membrane potential when the cell is at rest, typically around -70 millivolts. Membrane potential refers to the difference in electrical charge across the cell membrane. Resting potential is a type of membrane potential that is maintained when the cell is not actively sending signals.
What is the electrical potential across the cell membrane of a nerve cell or muscle cell when the cell is not active?
The resting membrane potential of a nerve cell or muscle cell is typically around -70 millivolts. This electrical potential is maintained by the unequal distribution of ions across the cell membrane, with more negative ions inside the cell than outside. This resting potential is essential for the cell to respond to changes in its environment and generate electrical signals when needed.
Why is resting stage a bad name for interphase?
The term "resting stage" is a misnomer because even though cells are not actively dividing during interphase, they are still carrying out important metabolic activities and preparing for cell division. Thus, the term "resting stage" can be misleading as it implies a lack of activity when there are actually significant processes occurring within the cell.
The state during which a neuron contains more negatively charged ions inside the cell than outside the cell and is not firing is referred to as the?
resting 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.
What is a small rounded thick walled resting cell?
endospore
Why is a blood cell rounded?
Ablood cell is a rounded so that it can move easily through small blood vessels.
When a cell is at rest?
resting potential
When conditions become unfavorable some bacteria produce a small internal resting cell called a capsule true or false?
false endospore

What is the difference in electrical charge across the cell membrane of a resting neuron is called?
This is the definition of "resting potential".
Do all cells have a resting potential of -70mV?
No, not all cells have a resting potential of -70mV. The resting potential of a cell can vary depending on the type of cell and its function. However, many excitable cells, such as neurons, have a resting potential close to -70mV.

The resting membrane potential of a nerve cell or muscle cell is typically around -70 millivolts. This electrical potential is maintained by the unequal distribution of ions across the cell membrane, with more negative ions inside the cell than outside. This resting potential is essential for the cell to respond to changes in its environment and generate electrical signals when needed.
How is a resting potential achieved in the nervous system?
The resting nerve cell is not being stimulated to send a nerve impulse
How do sodium ions move during resting potential?
During resting potential, sodium ions are actively pumped out of the cell by the sodium-potassium pump to maintain the concentration gradient. This helps to establish a more positive charge outside the cell, contributing to the negative resting membrane potential inside the cell. Sodium channels are closed during resting potential, preventing sodium ions from moving back into the cell.
