Increased oxygen consumption would accompany
A) increased heat production.
B) increased conversion of lactic acid to glucose.
C) increased aerobic respiration by muscle cells.
D) increased muscle activity.
E) all of the above

Question

Quizplus · Accepted Answer

Increased oxygen consumption is a sign of increased metabolic activity, which can result from any of the processes listed in the answer choices. Increased heat production and conversion of lactic acid to glucose both occur in response to increased metabolic demand, and both require increased oxygen consumption. Similarly, increased aerobic respiration by muscle cells and increased muscle activity both require more oxygen to support increased energy production. Therefore, all of the above choices are correct.
