The body, definition its by you looking at it, you can touch and feel, and it has to be vertical, so you will always always have an anatomy

I thought I always saying that.

So is there chemistry reaction inside the body?

That is called the biochem.

Is the enzymatic reaction is the chemistry reaction?

Its a bio reaction. It took place at? The bio living thing. 

Is the perspiration a bio reaction?

You normally characterize everything inside your cell membrane or within your body, organs, GI track, that is everything inside your body. Artery, veins, organs, GI track (hollow). When you saying perspiration, you mean an elimination process something forming outside your body. Its an excretion. You seeing that form outside your body.

Of course, its created out of your body, you eliminating your urine outside, your sweat outside. Its all part of the biological reaction, but I think if you concrete more of your thoughts in your own understanding

1. Is that molecular level

2. Signaling level (neuro transmission)

3. A dew is way bigger than you imagine any you saying the bio reaction inside your body that including the enzymatic reaction. 

4. You probably meant more all the reaction chart you memorize inside your biochem textbook, that is a feedback signaling system.

5. You didn't define the SIZE of your molecular level, your empirical formula idea....close to that idea, you are drawing? A structure inside your notebook, you trying to memorize this size of the diagram how to pass an exam, you didn't define me how it is inside or the outside body, and how big its this waste be eliminated, vanishing out of the body experience?
