Functional groups are responsible for chemical reactions of molecules.
Chemical because the molecules get rearranged making a entirely new molecule
Dehydration reactions involve the removal of a water molecule from two adjacent molecules. This process forms a covalent bond between the molecules, typically resulting in the formation of a larger molecule.
Condensation and hydrolysis are almost like opposite reactions. In condensation, two molecules react to form one larger molecule while giving off a smaller molecule such as water (hence the term condensation). The reverse occurs in hydrolysis where a molecule such as water attacks a larger molecule that is susceptible to hydrolysis and breaks it down into two smaller molecules.
I wouldn't think about it as things being destroyed. Chemical bonds are being modified during chemical reactions, so you may be breaking down a molecule into other molecules, or adding a piece on to a molecule, but you aren't really destroying or gaining anything new, just new forms. Energy can be either given off or "consumed" during a reaction.
It occurs 2x per glucose molecules.. But the thing is, I didn't know how that happen
Condensation reactions are so called because they involve the formation of a covalent bond between two molecules, resulting in the release of a small molecule such as water. This process "condenses" the two molecules together by removing a molecule of water.
When biological molecules engage in condensation reactions, they release a water molecule as a byproduct. These reactions are commonly involved in building larger molecules by linking smaller subunits together. Examples include the formation of peptide bonds in proteins and glycosidic bonds in carbohydrates.
Molocules do not make new elements. Elements only change during atomic reactions, primarily nuclear fusion in stars. The atoms in a molecule are always the same, during chemical reactions they are only being rearranged. The oxygen you breathe in and the carbon dioxide that you breathe out, for example, are made of the same oxygen atoms.
Chemical reactions are speeded up by enzymes (= proteins, = organic molecules) or more in general: by catalyst
