Question

The cell contains a number of impermeable molecules that carry negative charges including dna and proteins. If researchers removed all of the dna and proteins from the squid giant axon, what do you think would happen to the resting membrane potential of the cell?.

Answer 1

The resting membrane potential would become more positive because researchers are taking negatively charged molecules out of the cell.

Which methods were used to record the resting membrane potential and action potential of the squid axon choose all that apply ?

• The squid axon's action potential and resting membrane potential were captured using the following experimental strategy.
• Using a recording microelectrode inside the cell that is connected to a second electrode outside the cell .

What is cell membrane ?

• All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment.
  A semipermeable lipid bilayer makes up the cell membrane.
• The movement of materials into and out of the cell is controlled by the cell membrane.

What are the functions of a cell membrane?

• The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out .
• second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.
