Thermodynamics refers to the study of the transformation of energy, which occurs in a collection of matter. In carrying out the chemical reactions , living cells tends to convert the forms of energy to heat energy.

Question

When you exercise, your muscles are using ATP to do the movements. Thus, the cell is doing cellular respiration in order to replace the ATP it has used. A) Draw a series of diagrams showing the energy transfers that occur during exercise (include: ATP, muscle, heat, cell respiration, glucose). B) When we exercise, we produce a lot of heat, to cool us down, our body produces sweat. According to the laws of thermodynamics, where is the heat coming from? C) When we exercise to lose weight, where is that mass going (do we sweat it out, it turns into heat, becomes digestive waste, how do we eliminate it?)?
