Mitochondria have been suggested to be paramount for temperature adaptation in insects. Considering the large range of environments colonized by this taxon, we hypothesized that species surviving changes would those with most flexible mitochondria. We thus investigated responses mitochondrial oxidative phosphorylation (OXPHOS) three flying insects: honeybee (Apis mellifera carnica), fruit fly (Drosophila melanogaster) and Colorado potato beetle (Leptinotarsa decemlineata). Specifically,...
ABSTRACT The metabolic responses of insects to high temperatures have been linked their mitochondrial substrate oxidation capacity. However, the mechanism behind this flexibility is not well understood. Here, we used three insect species with different thermal tolerances (the honey bee, Apis mellifera; fruit fly, Drosophila melanogaster; and potato beetle, Leptinotarsa decemlineata) characterize sensitivity enzymes. Specifically, measured activity enzymes involved in glycolysis (hexokinase,...
Abstract The mechanisms that underpin aging are still elusive. In this study, we suggest the ability of mitochondria to oxidize different substrates, which is known as metabolic flexibility, involved in process. To verify our hypothesis, used honey bees ( Apis mellifera carnica ) at ages, assess mitochondrial oxygen consumption and enzymatic activities key enzymes energetic metabolism well ATP5A1 content (subunit ATP synthase) adenylic energy charge (AEC). We also measured mRNA abundance...
