What selects which molecules enter the cell?
Nuclear decide and allow which molecules will be enter in the cell,- Isrg Rajan
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.
Which substance may enter a cell membrane by simple diffusion?
Water, certain ions, air and glucose molecules.

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.
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
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.
Which substance may enter a cell membrane by simple diffusion?
Water, certain ions, air and glucose molecules.
What type of molecules pass through the cell membrane?
All ionic molecules and all large fat molecules. What can get in (without help) is water and dissolved gases.
What semipermeable is only allowed certain molecules to enter the cell?
cell membrane may be what you are looking 4
