What separates the cell from its surroundings and selects what can and can't enter?
Cell Membrane!!
How are amino acid molecules and fatty acid molecules the same?
amino acid molecules are water soluble meaning they cannot enter the cell. Fatty acid molecules CAN enter the cell.
The plasma cell membrane regulates which molecules can or cannot enter a cell since it is?
permeable (has channels/transporters for specific ions/molecules)
What type of molecules cannot enter the cell?
polar molecules are repelled by the cells electrical charge.
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.
What separates the cell from its surroundings and selects what can and can't enter?
Cell Membrane!!
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 are amino acid molecules and fatty acid molecules the same?
amino acid molecules are water soluble meaning they cannot enter the cell. Fatty acid molecules CAN enter the cell.
What key selects cell down one worksheet window from the active cell?
The down arrow key, the Return key or the Enter key.
As the concentration of molecules outside a cell increases more molecules will enter the cell?
the molecules are moving down their concentration gradient BACK NEXT
What term is used to describe how the cell selects what materials enter and leave the cell?
selectively permeable or differentially permeable membrane
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
The plasma cell membrane regulates which molecules can or cannot enter a cell since it is?
permeable (has channels/transporters for specific ions/molecules)
What type of molecules cannot enter the cell?
polar molecules are repelled by the cells electrical charge.
How do large polar molecules enter the cell?
The polar molecules goes through facillated diffusion. The molecules goes through the channel or membrane protein which then goes inside the cell.
What semipermeable is only allowed certain molecules to enter the cell?
cell membrane may be what you are looking 4
