What else can I help you with?
What molecules will move easily across the cell membrane: large proteins, starch, water, or DNA?
Water is the molecule that will move easily across the cell membrane. It can cross the membrane through special channels called aquaporins. Large proteins, starch, and DNA are too large to pass through the membrane without assistance.
Why can oxygen diffuse across s cell membrane but a protein cannot?
Oxygen can diffuse across a cell membrane because it is a small, non-polar molecule that can easily pass through the lipid bilayer of the membrane. In contrast, proteins are large and often polar or charged, making it difficult for them to traverse the hydrophobic core of the lipid bilayer without assistance. Proteins typically require specific transport mechanisms, such as channels or carriers, to facilitate their movement across the membrane.
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
Why can oxygen diffuse across the cell membrane the protein cannot?
Oxygen can diffuse across the cell membrane because it is a small, nonpolar molecule, allowing it to pass through the lipid bilayer easily due to the hydrophobic nature of the membrane. In contrast, proteins are larger and polar or charged, which prevents them from readily crossing the lipid bilayer without assistance. Instead, proteins typically require specific transport mechanisms, such as channels or carriers, to facilitate their movement across the membrane. This difference in size and polarity is key to the distinct transport processes for oxygen and proteins.
Why are Polar molecules unable to go across unless?
Polar molecules are unable to easily cross biological membranes because the interior of the membrane is hydrophobic, repelling the polar molecules. This prevents them from passing through via simple diffusion. To overcome this barrier, polar molecules usually require the assistance of specific transport proteins or channels to facilitate their movement across the membrane.

What is the transport of water across the cell membrane called?
Movement of water across a membrane is called OSMOSIS.
How plasma membrane diffuse across plasma membrane?
Ions can't diffuse across membranes, they must used channels to transport across
What is the equilibrium of solute across a membrane?
The equilibrium of solute across a membrane is reached when the concentration of the solute is the same on both sides of the membrane. This means that the movement of the solute molecules is balanced, with an equal number of molecules moving in and out of the membrane. At equilibrium, there is no net movement of solute across the membrane.

What does a carrier protein do in the process of transporting molecules across a cell membrane?
A carrier protein helps transport molecules across a cell membrane by binding to specific molecules and changing shape to move them across the membrane.
What is a membrane potential?
a voltage or electrical charge across the plasma membrane
Which one moves faster across the cell membrane the large or the small?
Small particles move faster across the membrane.
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
When will water stopping across a membrane?
When will water stop moving across a membrane when the water concentration is equal on both sides.
