Biological Chemistry of Organelle Formation

Eukaryotic cells comprise a plurality of organelles individual by means of their particular membranes and contents. Their biogenesis happens via development and department of preexisting buildings instead of de novo. Mitochondria and chloroplasts, which seem to be descended from prokaryotic ancestors, have retained a few DNA and the biosynthetic potential for its expression.

Collisions are represented then by a succession of vertices corresponding to transitions from the vacuum of correlation to the vacuum of correlation. The simplest collision (two vertices) is represented on Fig. 5 Figure 5. From the point of view of correlations it corresponds to the formation of a correlation involving one photon k and two atomic states which has a finite lifetime (this is by definition the “duration” of the collision). From the point of view of occupation numbers it corresponds to a change of 5 1 for two atomic states and of f1 for a photon state.

But when a value of p Z t can be found so that (pL,. , p Z k ) E M z k, I(S) lies between that for the latter and for (pi,. . , when k > 1, between finite limits. If, furthermore, (pl,. . , pzk-i) is such that (pi,. . , p Z k ) E M2k‘,the value of I ( S ) can be obtained as the limit of Z(S’) (S‘ assigning pl,. . ,p Z k ) as the moment point moves through MZk‘to a minimizing position. When extended to distributions in 3-momentum space, the above considerations lead to first-order approximations to macroscopic expressions, based on theorems rather than on uncontrolled formalism.
