What else can I help you with?
Water soluble molecules often enter or exit a cell in what process?
Water soluble molecules often enter or exit a cell through a process called facilitated diffusion. This process involves the movement of molecules across the cell membrane with the help of specific protein channels or carriers.
How do Lipid-soluble molecules and gases enter the cell?
diffusion through the lipid bilayer.
How does most water soluble materials get into a cell process by which molecules tend to move from an area of higher concentration to an area of lower concentration?
Most water-soluble materials enter a cell through the process of passive diffusion, where molecules move across the cell membrane from an area of high concentration to an area of low concentration. This movement occurs without the cell expending energy and helps maintain the balance of molecules inside and outside the cell.
Which molecules are passively absorbed into the blood?
Small, non-polar molecules like oxygen, carbon dioxide, and water can passively diffuse through cell membranes and be absorbed into the blood. Lipid-soluble molecules and small uncharged molecules can also passively cross cell membranes to enter the bloodstream.
How does the absorption of a water-soluble molecule differ from that of a fat-soluble molecule?
Water-soluble molecules are absorbed through passive diffusion or facilitated transport in the intestines, while fat-soluble molecules are absorbed with the help of bile salts and form micelles for absorption through simple diffusion in the small intestine. No specific transporters are needed for fat-soluble molecules due to their ability to pass through the cell membrane easily, unlike water-soluble molecules which require specific transporters for absorption.
How do fatty acid molecules differ from amino acid molecule?
amino acid molecules are water soluble meaning they cannot enter the cell. Fatty acid molecules CAN enter the cell.
Water soluble molecules often enter or exit a cell in what process?
Water soluble molecules often enter or exit a cell through a process called facilitated diffusion. This process involves the movement of molecules across the cell membrane with the help of specific protein channels or carriers.
Do lipid soluble molecules diffuse into a cell more rapidly than water soluble molecules?
Yes, lipid soluble molecules diffuse into a cell more rapidly than water soluble molecules. This is because the cell membrane is primarily made up of lipids, so lipid soluble molecules can easily pass through the lipid bilayer, while water soluble molecules need specific channels or transporters to facilitate their entry into the cell.
How do Lipid-soluble molecules and gases enter the cell?
diffusion through the lipid bilayer.

How does salts enter the cell?
Salts are soluble. The phospholipid bilayer membrane of cell walls are permeable to water and thus allow water and water-soluble substances, like salts, diffuse through.
Why will water-soluble molecules have a hard time moving through the lipid bilayer of a cell?
false
How does the absorption of a water-soluble molecule differ from that of a fat-soluble molecule?

No specific transporters are needed for fat-soluble molecules due to their ability to pass through the cell membrane easily, unlike water-soluble molecules which require specific transporters for absorption.
What organic molecule in cell membranes that permits the diffusion of lipid-soluble materials?
Phospholipids are the organic molecules in cell membranes that permit the diffusion of lipid-soluble materials. They have a hydrophobic tail that repels water and a hydrophilic head that interacts with water, creating a bilayer structure that allows for the passage of lipid-soluble molecules.
The fatty acid tail region of the phospholipids prevent soluble molecules from entering the cell?
Yes, the fatty acid tails of phospholipids are hydrophobic, which means they repel water-soluble molecules. This property creates a barrier that prevents those molecules from freely diffusing across the lipid bilayer of the cell membrane.
Why can only molecules that are fat soluable permate a cell membrane?
The cell wall itself is made of lipid. To be more precise, the cell membrane is made of a bilayer of phospholipids. The hydrophobic fatty acid tails prevent water-soluble molecules passing through, but allow the transport of lipid-soluble molecules.
