~ It is lost by the body in the form of heat.
D) It is lost by the body in the form of heat
To determine what happens to approximately 60% of the energy released during the complete oxidation of glucose, we can analyze the options given.
A) It is used to synthesize more ATP: During the process of cellular respiration, glucose is broken down into ATP (adenosine triphosphate), which is the primary energy currency of cells. However, the energy conversion efficiency of cellular respiration is not 100%, so this option may not explain what happens to the majority of the energy.
B) It is reused to supply the energy for anabolic reactions: Anabolic reactions are processes that build complex molecules from simpler ones, requiring an input of energy. While glucose metabolism can contribute to anabolic reactions, it is unlikely to account for 60% of the energy released.
C) It is stored in the body as fat: Glucose can be converted into fat for long-term energy storage. However, this option does not specifically address the proportionate amount of energy released during the oxidation of glucose.
D) It is lost by the body in the form of heat: This option suggests that a significant amount of energy is released as heat. Research has shown that the overall energy conversion efficiency of cellular respiration is less than 40%, with the majority of the energy being released as heat.
Therefore, the correct answer is D) It is lost by the body in the form of heat.
