Which ions are permeable to phospholipids that make up the plasma membrane?
which ions are permeable to phospholipids that make up the plasma membrane
Through the membrane of a resting neuron highly permeable to potassium ions its membrane potential does not exactly match the equilibrium potential for potassium because the neuronal membrane is?
Slightly permeable to sodium ions.
What ions are most permeable in neuron plasma membranes?
K+
Binding of the neurotransmitters with muscle membrane to become permeable to sodium and sodium ions is?
synapses
What is the function of the cell menbrane?
The cell membrane is selectively-permeable to ions and organic molecules and controls the movement of substances in and out of cells.

which ions are permeable to phospholipids that make up the plasma membrane
What is meant by partially permeable?
a partially permeable membrane allows some molecules or ions to pass through it

Slightly permeable to sodium ions.
What ions are most permeable in neuron plasma membranes?
K+
Binding of the neurotransmitters with muscle membrane to become permeable to sodium and sodium ions is?
synapses
What selectively permeable means?
Selectively permeable describes a cell membrane that allows certain ions or molecules to pass through it by means of passive or active transport.
How do the nodes of Ranvier differ from other segments of the same axon?
The nodes are more permeable to ions
What is meant by membrane is membrane?
a partially permeable membrane allows some molecules or ions to pass through it
The combining of the neurotransmitter with the muscle membrane receptors causes the membrane to become permeable to sodium ions and blank of the membrane?
Depolarization
What is the function of the cell menbrane?
The cell membrane is selectively-permeable to ions and organic molecules and controls the movement of substances in and out of cells.
What are mechanical gated channels?
Chemically-gated ion channels are receptor membrane proteins that are permeable to specific ions. The 'gating' part of it refers to the channel being open only once activated; which in this case will be by a chemical. An example would be the AMPA glutamate receptor, which has a channel pore that is permeable to sodium ions. Only by binding to glutamate (a neurotransmitter) does the channel allow sodium ions to enter the cell.
What is meant by the term differentially permeable?
The term differentially permeable refers to a membrane or barrier that allows specific molecules or ions to pass through while preventing others from passing. It is also known as selectively permeable or semipermeable. This property is essential for maintaining the balance of substances within cells and regulating the movement of molecules across biological barriers.
