Which solute is the least likely to cross a membrane by simple diffusion?
Large polar molecules and ions are the least likely to cross a membrane by simple diffusion due to their size and charge, which hinders their ability to pass through the hydrophobic lipid bilayer.
What structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not?
A large glucose molecule requires facilitated diffusion but an oxygen molecule does not is a semipermeable membrane.
What substances would most likely require a protein to facilitate its diffusion across a cell membrane?
Quick answer: glucose Explanation: Any substance that the membrane selects against requires integral proteins to cross the membrane. B/c the lipid bilayer is selectively permeable, not all substances can pass through it by diffusion or osmosis. However, when the cell requires a substance that it's membrane does not easily allow to pass through, it must enter via the proteins in the membrane. They can either be carrier proteins or protein channels depending on the substance. One example of a substance which requires facilitated diffusion is glucose.
Molecules A and B come in contact with the cell membrane of the same cell Molecule A passes through the cell membrane readilybut molecule B does not Which statement could describe molecules A an?
Molecule A is likely smaller and more hydrophobic, allowing it to pass through the cell membrane easily via simple diffusion. Molecule B may be larger, polar, or charged, requiring a transporter or channel for passage across the cell membrane.
Which of the following would likely move through the lipid bilayer of a plasma membrane most rapidly?
Small, nonpolar molecules such as oxygen and carbon dioxide would likely move through the lipid bilayer of a plasma membrane most rapidly due to their ability to dissolve in the hydrophobic core of the membrane.
Can partition coefficient influence passive diffusion rate?
Yes, the partition coefficient can influence passive diffusion rate by determining how easily a molecule can move across a membrane. A higher partition coefficient typically means the molecule is more likely to dissolve in the lipid bilayer of the membrane, thus facilitating faster passive diffusion. Conversely, a lower partition coefficient can slow down passive diffusion.
What type of molecule would be likely to diffuse across the phospholipid bilayer of the cell membrane?
an ion
Which structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not.?
A semipermeable membrane is a large glucose molecule that requires facilitated diffusion but an oxygen molecule does not.

What structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not?
A large glucose molecule requires facilitated diffusion but an oxygen molecule does not is a semipermeable membrane.
Where in the membrane does facilitated diffusion occur?
Diffusion will most likely to occur where there is a high concentration of gas or water then the particles distibute evenly to the area of low concentration. for example if you could smell a turkey cooking in the oven from upstairs without anyone telling you.
What kind of substances are likely to move via passive transport through phospholipod bilyer?
Small, non-polar molecules like oxygen and carbon dioxide are likely to move via passive transport through a phospholipid bilayer. These molecules can easily diffuse across the lipid bilayer due to their size and hydrophobic nature. Larger or polar molecules generally require other mechanisms such as facilitated diffusion or active transport to cross the membrane.
What substance is most likely to passively diffuse across the plasma membrane by dissolving in the membrane?
Nonpolar molecules like lipid-soluble substances (e.g., steroid hormones, oxygen, and carbon dioxide) are most likely to passively diffuse across the plasma membrane by dissolving in the lipid bilayer. This type of diffusion does not require a specific transport protein and can occur directly through the phospholipid bilayer due to the molecules' hydrophobic nature.
What substances would most likely require a protein to facilitate its diffusion across a cell membrane?
Quick answer: glucose Explanation: Any substance that the membrane selects against requires integral proteins to cross the membrane. B/c the lipid bilayer is selectively permeable, not all substances can pass through it by diffusion or osmosis.

Molecule A is likely smaller and more hydrophobic, allowing it to pass through the cell membrane easily via simple diffusion. Molecule B may be larger, polar, or charged, requiring a transporter or channel for passage across the cell membrane.
Would oxygen particles enter a cell through diffusion more likely than fat particles?
Yes, oxygen particles would enter a cell through diffusion more readily than fat particles due to their smaller size and higher solubility in the cell membrane. Fat particles are larger and less likely to pass through the cell membrane via simple diffusion.
What is the difference of facilitated diffusion with the help of a carrier molecule and active transport with the help of a transport protein?
The carrier mole accompanies the transported mole through the plastic brain, and is then sent across the bran.sport teens channels are most likely very large and are as such bedded in the bi layer!
