Honeybees Rely Primarily on the Oxidation of Hexose Sugars to Provide the Energy Required for Flight. Measurement of VCO2 (Equal to VO2, Because VCO2/VO2 = 1.0 during Carbohydrate Oxidation) during Flight Allowed Estimation of Steady-State Flux Rates through Pathways of Flight Muscle Energy Metabolism. Comparison of V(Max) Values for Flight Muscle Hexokinase, Phosphofructokinase, Citrate Synthase, and Cytochrome C Oxidase with Rates of Carbon and O2 Flux during Flight Reveal that These Enzymes Operate Closer to V(Max) in the Flight Muscles of Flying Honeybees Than in Other Muscles Previously Studied. Possible Mechanistic …
