In the rusty crayfish (Orconectes rusticus), toxicity of copper at high concentrations is due to the coagulatory action on cellular proteins and to interference with respiratory processes at low concentrations, copper causes degenerative changes in certain tissues and interferes with glutathione equilibrium (Hubschman 1967). Larvae of the red crayfish (Procambarus clarkii) exposed to copper as embryos are less sensitive than those exposed after hatching, suggesting acclimatization (Rice and Harrison 1983).

Excessive amounts of arsenic can cause skin, lung, and heart diseases, and gastrointestinal disorders, and it is known to have a carcinogenic influence. As" " compounds, which are bound by erythrocytes, affect the activity of numerous enzymes - especially those involved in respiratory processes (Cebrian et al., 1983 Done and Peart, 1971 National Academy of Sciences, 1977 WHO, 2001). 

Damage to the mitochondria and the intracellular respiratory processes. Damage to this organelle has been detected soon after exposure to the nephrotoxic cephalosporins along with reduced mitochondrial respiration (Fig. 7.35). 

I must admit that this first visual perception of an intracellular respiratory process was one of the most impressive spectacles I have witnessed in the course of my work. Now I have no doubt that cytochrome is not only widely distributed in nature and completely independent of haemoglobin, but that it is an intracellular respiratory pigment which is much more important than haemoglobin. 

Both of these systems are apparently closely linked to respiratory processes and m this sense are analogous to one another. Luciferase from a luminous bacterium. Photobacterium fischen, has been made into-crystal in high yield.

The overall equation of the respiratory process is described by a chemical equation of the exergonic type ... 

It should be remembered that oxidative phosphorylation is conjugated with the respiratory process and, therefore, the question of where H+ ions come from can be simply answered. At ATP synthesis, the respiratory chain releases H+ ions to the system during electron transfer, and the electron transfer energy is consumed for H+ generation. 

Thus, the excessive concentration of hydrogen ions represents a highly active intermediate compound of two conjugated reactions the respiratory process, on the one hand, and the oxidative phosphorylation, on the other. 

However, it should be noted that the two hypotheses under consideration conform to each other, and they may not be considered as alternatives to one another. Most likely, they complement each other and decode the consumption mechanism of chemical energy released during respiratory processes and its accumulation shaped as high-energy bonds (ATP). 

Enzymatic activity of the substrate in the respiratory process (3.49) is implemented by Krebs cycle hydrogenases (3.52) (the endergonic component of the respiratory process), where chemical energy is accumulated in the form of an active intermediate compound (linked hydrogen atom). There is no doubt that linked 8H and 2C02 forms, in which these intermediates exist in the cell environment, will significantly decrease AG° [21]. The final product of the respiratory process is synthesized by enzymes of the respiratory chain (exer-gonic component). 

Apparently, experiments with labeled proton donor (e.g. CD3 or COOD) should be implemented. Then the reaction of deuterium ions will produce the expected labeled water in the respiratory process, which will unambiguously indicate the validity of the suggested mechanism. 

Figure 8.21 Porewater size/reactivity model (PWSR) model used to describe the cycling of DOM in sediments. Similar to remineralization of POM described earlier for the water column, sedimentary POM is initially hydrolyzed by bacteria in the benthos to HMW DOM this is further hydrolyzed to monomeric LMW DOM (mLMW DOM)—these small molecules (e.g., amino acids, monosaccharides) are used in other respiratory processes by bacteria in sediments. H = HMW DOM, P = polymeric LMW DOM (pLMW DOM), = rate constant for HMW DOM consumption, Ap = rate constant for pLMW DOM consumption, and a = fraction of HMW DOM consumption that passes through the pLMW DOM pool.

The respiratory rate of chlorophyllous tissue as measured by the loss of C02 from the tissue proceeds at a higher rate in the light than in the dark. This light-stimulated loss of carbon, termed photorespiration, is a process that is in addition to or superimposed on the normal dark respiratory process in the plant. A significant portion of the carbon that is fixed in many species actually moves through the photorespiration pathway. In C3 species such as Jerusalem artichoke, it is estimated that between 30 and 50% of the photosynthetically assimilated carbon in the leaves may be lost through the process of photorespiration.
