Question

What is Dehydration synthesis AND Hydrolysis? include an example for each that would affect a living organism?

the part i really need is the examples, i'm struggling to find any

Answer 1

Dehydration synthesis links two monomers by removing a water from two adjacent hydroxyl groups (-OH); Hydrolysis is the opposite, inserting a water into a polymer to break it up into its monomers.

Explanation:

When your body is queued by insulin, it removes glucose from the bloodstream and stores it as the molecule glycogen (animal starch) - many glucose are linked together into a chain through dehydration synthesis.

When your body is queued by the hormone glucagon, glycogen is broken down into its glucose monomers via hydrolysis and released into the bloodstream.

I like this example because it illustrates the homeostatic mechanism for inverse feedback inhibition between hormones - a common process found in animals.
