Flying insects do all of the following except
A) increase metabolism as much as 200-fold during flight.
B) switch from diffusion of tracheal gases to active transport during flight.
C) utilize high numbers of mitochondria in flight muscles.
D) produce water molecules from oxygen in mitochondria.
E) generate carbon dioxide from catabolism of fuel molecules.

Question

Quizplus · Accepted Answer

Insects increase their metabolism significantly during flight, utilize a high number of mitochondria in their flight muscles for energy, produce water molecules from oxygen in mitochondria during cellular respiration, and generate carbon dioxide from the catabolism of fuel molecules. However, they do not switch from diffusion of tracheal gases to active transport during flight; instead, they continue to rely on the efficient diffusion process through their tracheal system to meet their oxygen demands.
