THE LIMITS OF DIVISIBILITY OF LIVING MATTER THE preceding lecture has shown that living matter is a mixture of various compounds, namely proteins, fats, carbohydrates, and salts. The fact that the reaction velocity for a number of oxidative and hydrolytic processes is so great, in spite of the low temperature and the practically neutral reaction of the tissues, has found its explanation through the presence of specific enzymes and the intermediary reactions determined by them. If we ask whether

The participation of oxygen as the terminal electron acceptor in oxidative phosphorylation has conferred a marked superiority on respiration over fermentation, in the efficiency of converting the free energy of substrate into the energy of the pyrophosphate bonds of ATP.

They also show that salts or elec- trolytes were probably no longer present in the cells and that oxidative processes had ceased, because the simple addition of salts to the medium resulted in the restoration of vital activities. Finally they indicate that the nucleus of the cell is probably the seat of manufacture of the oxidative ferments or catalyzers.. Please note that these images are extracted from

Known as ATP synthase, the enzyme complex (two shown) is embedded in the mitochondrial inner membrane (orange, across bottom). The lower part is a channel through which protons (yellow dots) move. The upper part is where ATP synthesis takes place. ATP is formed from a reaction between ADP (adenosine diphosphate) and inorganic phosphate (both shown in orange).

NUCLEOTIDES AND MITOCHONDRIAL FUNCTION 231 These results show that added ATP can influence the redox state of intramitochondrial components of hydrogen transfer such as DPX and flavoprotein. It is to be assumed that ATP exerts its influence through back reactions of oxidative phosphorylation. The energy requirement for the DPX reduction in the presence of succinate or glycerolphosphate—so far only postulated on the basis of thermodynamic reasoning—has been directly demonstrated bv these experiments.

BIOLOGICAL TRANSPORT in a sequence, not only can metabolism be the cause of transport, but also transport can be the cause of metabolism. Thus, we might be inclined to recognize that transport and metabolism, as usually understood by biochemists, may be conceived advanta- geously as different aspects of one and the same process of vec- torial metabolism. In this hypothesis (Figure 27) the process of oxidative phos- phorylation is seen as a transport, which may be linked to electron transport but which, presumably, may equally
