A Pair of Fives

Hormones make the Endocrine System work 
They’re always around, they always lurk. 
And they do so many things
And to the body the blood always brings
So many chemicals all over abound
Each only binds to specific receptors found.
Sometimes they’re high, sometimes they’re low 
And hormones always absolutely go 
Via the blood until it finds, 
Its special receptor, where it binds. 
And no matter what you think you knew
There’s only five things they generally do.

Membrane potential, a hormone can alter, 
And so a cell’s function will never falter.
When they alter membrane potentials we know
And that always means information will flow.

Protein synthesis, too, gets involved 
And making large molecules soon gets resolved. 
They can cause proteins synthesis in the cell
By turning on genes that work so well.

Enzyme modifications are also the norms
They can activate second messenger forms.
And when it does, it can certainly cause, 
Enzyme activity or enzyme pause. 

Secretions, too, the cell will spit out, 
Due to the hormone, because of its clout. 
And what is the importance of what the hormones’ issues
These cells spew out substances to affect other tissues.

Then there’s the last, reproductive in nature
Mitosis and meiosis, both important in stature.
Both types of cell division are obviously affected, 
Another example of hormones, reflected.
