permeable

Examples of permeable in the following topics:

• Alteration of Membrane Permeability

  • However, it still increases the permeability of the bacterial cell wall to other antibiotics, indicating that it causes some degree of membrane disorganization.
  • Gramicidin's bactericidal activity is a result of increasing the permeability of the bacterial cell membrane, allowing inorganic monovalent cations (e.g.
  • The channel is permeable to most monovalent cations, which move through the channel in single file.
  • In the presence of a second type of permeable ion, the two ions couple their flux as well.
  • It has a permeability ratio of 2.9.

• Osmotic Pressure

  • Osmosis is the net movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration.
  • Osmosis is essential in biological systems because biological membranes are semi permeable.
  • However, they are permeable to non-polar and/or hydrophobic molecules like lipids as well as to small molecules like oxygen, carbon dioxide, nitrogen, nitric oxide, etc.

• Gram-Negative Outer Membrane

  • In Gram-negative bacteria the outer membrane is usually thought of as part of the outer leaflet of the membrane structure and is relatively permeable.

• Gas Vesicles

  • They are made up of a shell of protein that has a highly hydrophobic inner surface, making it impermeable to water (and stopping water vapor from condensing inside), but permeable to most gases.

• Injuring the Plasma Membrane

  • The plasma membrane is selectively permeable to ions and organic molecules.

• Bacterial Transformation

  • Artificial competence can be induced in laboratory procedures that involve making the cell passively permeable to DNA, by exposing it to conditions that do not normally occur in nature.
  • It is suggested that exposing the cells to divalent cations in cold condition may also change or weaken the cell surface structure of the cells making it more permeable to DNA.

• Chemical Analysis of Microbial Cytoplasm

  • The bacterial cytoplasmic membrane plays a role in permeability and energy conservation in microbial cell structure.

• Osmotic Pressure

  • It is also defined as the minimum pressure needed to nullify osmosis.The phenomenon of osmotic pressure arises from the tendency of a pure solvent to move through a semi-permeable membrane and into a solution containing a solute to which the membrane is impermeable.

• The Cardiovascular System

  • Blood vessel permeability is increased in inflammation.

• The Complement System

  • Both C3a and C5a have anaphylatoxin activity, directly triggering degranulation of mast cells, as well as increasing vascular permeability and smooth muscle contraction.
