To maintain high efficiency and greater power output with increasing wing beat frequencies,insect flight muscles have evolved
A) a high ratio of muscle contractions to excitation events.
B) a high ratio of actin to myosin.
C) a nonsliding filament contraction mechanism.
D) fast T tubules.
E) gap junctions.

Question

Quizplus · Accepted Answer

A high ratio of muscle contractions to excitation events allows insect flight muscles to maintain high efficiency and greater power output with increasing wing beat frequencies. This means that the muscles are able to contract more frequently in response to electrical signals from the nerves, allowing for rapid and efficient movement.
