Free palmitate is activated to palmitoyl-CoA in the cytosol before it can be oxidized in the mitochondria. If palmitate and [14

C]CoA are added to a liver homogenate, palmitoyl CoA isolated from cytosolic fraction is radioactive, but that isolated from the mitochondrial fraction is not. Explain.

<h2>Fatty acid oxidation </h2>

Explanation:

  • Activation of fatty acids (palmitate) occurs in the cytoplasm where fatty acids are activated to fatty acyl CoA, reaction catalysed by an enzyme called fatty acyl CoA synthetase
  • A specialized carnitine carrier system catalyze transportation of activated fatty acid from cytoplasm to matrix of mitochondria, where carnitine system consists of three proteins:
  • Carnitine acyl transferase I located in outer membrane of mitochondria catalyze transfer of carnitine to fatty acyl CoA and produce fatty acyl carnitine
  • Carnitine translocase facilitate passive diffusion of fatty acyl carnitine from inter membrane space to matrix located in inner membrane
  • Carnitine acyl transferase III located in inner mitochondrial membrane at matrix phase catalyze transfer of CoA to fatty acyl carnitine and regenerate fatty acyl CoA

Hence, the cytosolic and mitochondrial pools of CoA are thus kept separate, and no radioactive CoA from the cytosolic pool enters the mitochondria

Some examples of non-polar molecules include fats, oils, and waxed. How do these substances interact with water?
77julia77 [94]
Since non-polar molecules are equally distributed and positively charged atoms in contrast with polar molecules. Thus, like fats oils and waxes, these materials are composed mainly of lipids or in the group of fats and are conspicuously insoluble with water. How do these substances interact with water? They are hydrophobic, thus, they don't "mix" with water. Unlike water and other polar molecules that are unequally and negatively distributed and charged making them able to bond with other molecules like oxygen and other polar molecules and substances.

When the ATP synthase molecules are open, the hydrogen ions move out of the thylakoid. How does the cell use the kinetic energy
morpeh [17]

The synthesis of ATP is based on energy conversion, via conformational changes of the subunits.

A proton gradient on either side of the membrane into which the ATP synthases are inserted is necessary for their operation, which implies that the synthesis of ATP can not be done independently of a membrane. Within the mitochondrial inner membrane, it is the respiratory chain that provides the pH gradient by injecting protons into the intermembrane space during the transfer of electrons from one complex to another. At the level of the thylakoid membrane, it is the photosynthetic chain that injects protons into the lumen.
