RESPIRATORY ADAPTATIONS: INVERTEBRATES

摘要: The major recent advances are: (1) increased precision in describing the relation of oxygen consumption to concentration, temperature, and activity; (2) recognition cessation survival prolonged anoxia as common features invertebrate respiration; (3) integration data on properties enzymes pathways metabolism into developing story respiration with without oxygen. Variation rates uptake content medium can be described by a quadratic equation three parameters chosen express departure from strict conformity. Over certain segments environmental range, some species increases temperature only 1.2 1.4 times for 10°, rather than accordance expected doubling rate chemical reactions. When animals survive very low tension extended periods, they may called “euryoxic”, new term analogous euryhaline eurythermal. “facultative anaerobe” is inappropriate because all are aerobes. At least five bivalve mollusks highly euryoxic, surviving 21 51 days lack at temperatures. Since enzyme activity utlimately determine acid production, kinetic enzymes, together endogenous concentrations substrates, activators, inhibitors, must eventually predict rates.
