What else can I help you with?
What type of molecules cannot enter the cell?
polar molecules are repelled by the cells electrical charge.
Large molecules are surrounded by the cell membrane and enter the cell?
Large molecules can enter cells through processes like endocytosis, where the cell membrane surrounds the molecule and engulfs it in a vesicle. This allows large molecules to be transported into the cell without crossing the lipid bilayer of the membrane.
What separates the cell from its surroundings and selects what can and can't enter?
The cell membrane separates the cell from its surroundings and controls what can enter and exit the cell through a selective barrier called the lipid bilayer. This barrier allows certain substances, such as nutrients and waste, to pass through while blocking others.
What must the molecules in a capillary enter before they enter the cell?
Molecules traveling within the bloodstream pass through the capillary cell wall via osmotic pressure and diffuse through the interstitial fluid before encountering the tissue cell wall.
Cell membranes usually allow what substances to enter a cell?
Cell membranes usually allow water, gases (such as oxygen and carbon dioxide), and small uncharged molecules to enter a cell. Larger molecules or charged ions may require specific transport proteins or channels to cross the membrane.
What key selects cell down one worksheet window from the active cell?
The down arrow key, the Return key or the Enter key.
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.
How does a cell allow small molecules enter and exit?
"The cell membrane has openings in it." (PLATO) (:
What cell organelle has pores that allow certain molecules to leave and enter it?
Cell membrane

As the concentration of molecules outside a cell increases more molecules will enter the cell?
Yes, this process is known as osmosis. Water moves from an area of low solute concentration (outside the cell) to an area of high solute concentration (inside the cell) to balance the concentration levels. This causes more molecules to enter the cell as the concentration difference increases.
Cell membranes usually allow what substances to enter a cell?
Cell membranes usually allow water, gases (such as oxygen and carbon dioxide), and small uncharged molecules to enter a cell. Larger molecules or charged ions may require specific transport proteins or channels to cross the membrane.
What semipermeable is only allowed certain molecules to enter the cell?
cell membrane may be what you are looking 4
What is it called when part of a cell membrane closes around a molecule to allow the molecules to enter the cell?
Endocytosis
