Abstract:

The energy used by insect muscle in maintenance of tension and performance of work that, at times, can total more than a million successive wingbeats with rates over a thousand contractions per second is ultimately derived from chemical reactions going on within the muscle. The nature of these reactions is the subject of this report. It is proposed in the sections that follow to 1 examine the magnitude of energy expenditure by active muscle, 2 describe the mobilization of energy-rich reserves and their catabolism in muscle, 3 detail the chemical reactions that conserve chemical-bond energy and provide the contractile elements with energy in a readily utilizable form, and 4 discuss some biochemical-morphological interrelation-ships in functionally different muscles.
