Which of these extracellular signal molecules could diffuse through a plasma membrane and bind to an intracellular receptor?
estrogen
What is a transport process by which gases move through a membrane?
Simple Diffusion
Do water molecules passively enter and leave cells through the plasma membrane?
Yes, the direction of the flow depends on the contentration of water on the out side and the inside of the cell's membrane.
Why is digestion and absorption of lipids more complex than carbohydrates?
because lipids are nonpolar and cannot be transported as free fatty acids through the water-filled plasma membrane of the blood
What is the definition of protein gate?
A protein gate is a pathway through a protein molecule on the plasma membrane in which ions and small molecules can diffuse in or out of a cell.

What does not freely diffuse through the plasma membrane?
glucose
What substance is most likely to passively diffuse across the plasma membrane by dissolving in the membrane?
Lipid-soluble molecules such as O2 and CO2 diffuse freely through the plasma membrane.
What Substances that can freely dissolve through the plasma membrane are made of?
Substances that can freely pass through the plasma membrane must be small and non-polar.
How do lipid or oil get through plasma cell membrane?
Lipids or oil get through plasma membrane because plasma membrane is a selectively permeable membrane. It allows entry and exit of only some substances through it.
Which of these extracellular signal molecules could diffuse through a plasma membrane and bind to an intracellular receptor?
estrogen
Can lipids dissolve in blood plasma?
Plasma is mostly water, so no, lipids don't usually dissolve.
What is the nonliving matrix of the connective tissue through which the blood cells freely flow?
plasma
What is the main reason Na and K ions CANNOT easily diffuse through plasma membranes?
they are hydrophilic and can't cross the hydrophobic region of the plasma membrane
What is a transport process by which gases move through a membrane?
Simple Diffusion
Transport protein that provides a tubelike opening in the plasma membrane through which particles can diffuse?
Channel Protein.
How plasma membrane diffuse across plasma membrane?
Ions can't diffuse across membranes, they must used channels to transport across
