How does oxygen cross a selectively permeable membrane?
diffusion
Gases such as oxygen and carbon dioxide cross the plasma membrane by?
passive diffusion through the lipid bilayer
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 membrane do protons cross in the synthesis of ATP?
the messianinic membrane
What materials crossed the membrane and why did they cross?
Materials that can cross the cell membrane include small non-polar molecules like oxygen and carbon dioxide, as well as small polar molecules like water. These molecules can freely pass through the lipid bilayer of the membrane due to their small size and compatibility with the hydrophobic environment of the lipid tails. However, larger molecules and charged ions require specific protein channels or transporters to cross the membrane.
Why can oxygen easily cross the plasma membrane but sodium ions are unable to cross the plasma membrane?
Gh

What needs to get into the cell and cross the cell membrane?
Oh things like food, oxygen, ions, and even hormones.
How does Oxygen cross cell membrane?
Oxygen and water molecules can penetrate the cell membrane due to small gaps that are created by the lipid molecules. Lipid molecules overlap each other which makes the gaps. The oxygen and water molecules then enter in the gaps. The cell membrane in this case is semi permeable.
What is the membrane called if other substances besides water oxygen carbon dioxide and glucose are blocked from entering?
A semi-permeable membrane. Does cross - membrane transit of glucose need active transport,
What properties of carbon dioxide and oxygen allow them to easily cross a membrane?
i believe its their small size-- low atomic weight.
How does CO2 cross the cell membrane?
No, carbon dioxide does not need a transport protein to cross the cell membrane. It can pass through a membrane by diffusion.
Why can oxygen diffuse across a cell but a protein cannot?
Oxygen is much smaller than a protein.proteins are too largeDifference in size
What membrane do protons cross in the synthesis of ATP?
the messianinic membrane
