Inner Membrane

An Inner Membrane is a Biological Membrane within the Outer Membrane that is composed of a Phospholipid Bilayer.

• Context:
  • It includes a Cytochrome.
  • It can be:
    • a Prokaryote Inner Membrane.
    • an Eukaryote Inner Membrance.
• See: Periplasmic Space, Cytoplasmic Membrane, Nuclear Envelope, Mitochondria, Chloroplast, Organelle, Gram-Negative Bacteria.

  • The inner membrane is the biological membrane (phospholipid bilayer) of an organelle or Gram-negative bacteria that is within an outer membrane.
  • In eukaryotic cells, this inner membrane is present within the nuclear envelope, mitochondria and plastids like the chloroplast. The lumen between the inner and outer membranes is referred to as intermembrane space.
  • In prokaryotic cells such as many Gram-negative bacteria, the space between the inner and outer membrane is commonly referred to as the periplasmic space or periplasm. The inner membrane may also be referred to as the cytoplasmic membrane and it is similar in structure and protein content as the cytoplasmic membrane of other bacteria that contain only one membrane (such as most Gram-positive bacteria).
  • This structural arrangement of an inner and outer membrane is thought to be similar in Gram-negative bacteria, mitochondria and chloroplasts due to their ancestral relationship, as outlined in the endosymbiotic theory.

    • A membrane structure formed of two closely aligned lipid bilayers that lie beneath the plasma membrane and form part of the pellicle surrounding an apicomplexan parasite cell. [source: GOC:mah, PMID:12456714]
