Anaerobic Energy Metabolism

  title={Anaerobic Energy Metabolism},
  author={Gerd G{\"a}de},
When considering anaerobic energy metabolism, many people are unaware that it occurs in insects at all. This may be easily explained by the general knowledge that the energy metabolism of insect flight muscles is highly aerobic. It is well-known that insect flight muscles are metabolically the most active tissues known in nature. Their performance can be quite incredible; in some species more than one million successive wingbeats, with rates over 1000 contractions per second, have been found… 
Flight respiration and energetics.
Comparisons of related fliers and runners suggest that fliers generally have higher aerobic metabolic capacities than runners but that the difference is highly dependent on the taxa studied.

Biochemistry and Evolution of Anaerobic Energy Metabolism in Eukaryotes
The gene distribution across lineages reflects the presence of anaerobic energy metabolism in the eukaryote common ancestor and differential loss during the specialization of some lineages to oxic niches, just as oxphos capabilities have been differentially lost in specialization to anoxic niches and the parasitic life-style.

A consideration of chemical, fossil and functional approaches to the reconstruction of the beginning of life suggests an early role for the opine pathways in providing energy for the burrowing of infaunal worms of the Precambrian era.
Metabolic Rate Depression and Biochemical Adaptation in Anaerobiosis, Hibernation and Estivation
The present review focuses on the molecular control mechanisms that regulate and coordinate cellular metabolism for the transition into dormancy, which form a common molecular basis for metabolic depression in anoxia-tolerant vertebrates and invertebrates, hibernation in small mammals, and estivation in land snails and terrestrial toads.
Flexibility in energy metabolism supports hypoxia tolerance in Drosophila flight muscle: metabolomic and computational systems analysis
Simulations supported the hypothesis that the ability to flexibly convert pyruvate to these three by‐products might convey hypoxia tolerance by improving the ATP/H+ ratio and efficiency of glucose utilization.

Systems biology of the cardiac hypoxia response in Drosophila
A systems biology approach is adopted to discover important hypoxia-tolerance strategies in ATP-generating metabolism in Drosophila heart and offers clues to Hypoxia tolerance in flies, generating hypotheses for further research, and provides a technology platform for a systematic perturbation analysis.
In vivo Studies of the Acid-Base Physiology of Grasshoppers: The Effect of Feeding State on Acid-Base and Nitrogen Excretion
It is reported here that starved locusts (Taeniopoda eques) excrete net acid in the form of titratable acid and ammonium, the first report of flexible titRatable acid-base excretion in insects in vivo.

Invaginations of cuticle to form lungs or tracheae occurred independently multiple times across the Arthropoda and Pancrustacea in association with the evolution of terrestriality, suggesting that the tracheated hexapods likely evolved from Remipedia-like ancestors on land.
