What is pore protein?
integral protein that embedded to the plasma membrane. Allow small substances to cross the plasma membrane.
How does nitric oxide cross the plasma membrane?
Simple Diffusion
How does nutrients cross plasma membrane?
Things like oxygen, CO2 and lipids cross the membrane with simple diffusion. Water can cross the membrane with osmosis when the water moves through a channel protein in the plasma membrane. Glucose, potassium, sodium etc. moves through a carrier protein in the membrane with the process of active movement. In the process of active movement energy is needed and it is given by the glucose or ATP from the cell.
What helps to allow materials to cross the plasma membrane?
Integral proteins - proteins which span the width of the membrane. This can be things such as channels and pumps.
Do protein channels allow small charged molecule to cross the cell membrane?
Yes
Why can oxygen easily cross the plasma membrane but sodium ions are unable to cross the plasma membrane?
Gh

Ions cannot cross back and forth across the neuron cell membrane?
Water diffuses across the plasma membrane, and this can affect cell size and .... proceeds, the different type cells of the embryo develop their ... or ion so that it can cross the plasma .... molecules cannot cross the membrane because they are un- able to ... plasma membrane and the back and forth arrows indicate that these.
What are the compounds find it difficult to cross the plasma membrane?
