  2. Membrane potential - Wikipedia

    en.wikipedia.org/wiki/Membrane_potential

    In essence, the Goldman formula expresses the membrane potential as a weighted average of the reversal potentials for the individual ion types, weighted by permeability. (Although the membrane potential changes about 100 mV during an action potential, the concentrations of ions inside and outside the cell do not change significantly.

  3. VDAC1 - Wikipedia

    en.wikipedia.org/wiki/VDAC1

    Voltage-dependent anion-selective channel 1 (VDAC-1) is a beta barrel protein that in humans is encoded by the VDAC1 gene located on chromosome 5. [4] [5] It forms an ion channel in the outer mitochondrial membrane (OMM) and also the outer cell membrane. In the OMM, it allows ATP to diffuse out of the mitochondria into the cytoplasm. In the ...

  4. Proton pump - Wikipedia

    en.wikipedia.org/wiki/Proton_pump

    The F-type proton ATPase is a multi-subunit enzyme of the F-type (also referred to as ATP synthase or F O F 1 ATPase). It is found in the mitochondrial inner membrane where it functions as a proton transport-driven ATP synthase. In mitochondria, reducing equivalents provided by electron transfer or photosynthesis power this translocation of ...

  5. Prenatal testing - Wikipedia

    en.wikipedia.org/wiki/Prenatal_testing

    There are three purposes of prenatal diagnosis: (1) to enable timely medical or surgical treatment of a condition before or after birth, (2) to give the parents the chance to abort a fetus with the diagnosed condition, and (3) to give parents the chance to prepare psychologically, socially, financially, and medically for a baby with a health problem or disability, or for the likelihood of a ...

  6. Voltage-dependent anion channel - Wikipedia

    en.wikipedia.org/wiki/Voltage-dependent_anion...

    Voltage-dependent anion channels, or mitochondrial porins, are a class of porin ion channel located on the outer mitochondrial membrane. [1] [2] There is debate as to whether or not this channel is expressed in the cell surface membrane. [3] [4] [5]

  7. Fetal fibronectin - Wikipedia

    en.wikipedia.org/wiki/Fetal_fibronectin

    Fetal fibronectin is found normally in vaginal fluid in early pregnancy prior to 22 weeks due to normal growth and development of tissues at the junction of the uterus and amniotic sac. It may also be found in vaginal fluid after 36 weeks as labor approaches. However, fFN should not be detected between 22 and 36 weeks. [1]

  8. Adenine nucleotide translocator - Wikipedia

    en.wikipedia.org/wiki/Adenine_nucleotide_trans...

    The relationship of these parameters can be expressed by an equation solving for the 'reversal potential of the ANT" (Erev_ANT), a value of the mitochondrial membrane potential at which no net transport of adenine nucleotides takes place by the ANT. [14] [15] [16] The ANT and the F0-F1 ATP synthase are not necessarily in directional synchrony. [14]

  9. Mitochondria associated membranes - Wikipedia

    en.wikipedia.org/wiki/Mitochondria_associated...

    The mitochondria-associated ER membranes (MAMs), play role in cell death modulation. Mitochondrial outer membrane permeabilization (MOMP), is a reason of the higher matrix Ca 2+ levels, which is acts as a trigger for apoptosis. MOMP is the process before apoptosis, which is accompanied to permeability of the inner membrane of the mitochondria ...
