Document Summary
Metabolism: enzyme driven chemical reactions that convert chemical energy into molecular structures, mechanical work and heat. Consumed energy: chemical energy that has been converted into heat or mechanical work. Metabolic rate: rate of energy consumption (measured in j/s or w) Measure od the respiration of an animal assumes aerobic respiration and depends on the type of food you consumed: direct measurement of metabolic rate = how much heat and mechanical energy is generated by your body/second. Many of metabolic processes in our body depend on respiration. Metabolic rate depends on body size: pound per pound, larger animals burn less energy as compared to smaller animals. A weight-specific bmr (on log scale) vs. body weight (on log scale) has a negative slope. A log metabolic rate vs log body mass graph has a positive slope. Atp (adenosine triphosphate) is how energy is stored in the body.
