Where do nearly all of the body's chemical reaction, including those that produce energy and build new tissues, take place?

The right answer is aqueous medium (or water solution).

Because of its ubiquity, water has long been considered an inert liquid simply filling the intermolecular spaces in living organisms. It represents about 65% of the mass of living beings. All constituents of the cell "bathe" in an aqueous environment. It is in this environment that the exchanges between the cells take place, that the reactions of the metabolism take place, etc.

the more fit you are, the faster the recovery. your heart rate drops most sharply in the first minute after you stop exercising; it should then fall about 20 beats a minute—a drop of less than 12 beats a minute is considered abnormal. this “recovery heart rate” is measured as part of an exercise stress test.
